What is Cartalax 20mg (Bioregulator)

Cartalax 20mg (Bioregulator) is a synthetic peptide bioregulator belonging to the class of tissue-specific oligopeptide complexes. Cartalax is specifically designed as a research tool for studying the molecular mechanisms of cartilage and connective tissue biology, with particular focus on chondrocyte function and extracellular matrix (ECM) homeostasis.

Peptide bioregulators are short-chain oligopeptides (typically 2-4 amino acids in length) that function as signaling molecules in cellular communication networks. Unlike larger peptides that act as hormones or growth factors, bioregulators are hypothesized to operate through direct interaction with nuclear chromatin, influencing gene expression patterns in a tissue-specific manner. This class of compounds is based on research into tissue-specific peptide bioregulation.

Cartalax is derived from research on cartilage tissue and is used to investigate:

• Chondrocyte proliferation and differentiation

• Cartilage extracellular matrix synthesis and maintenance

• Collagen type II and aggrecan production

• Articular cartilage homeostasis

• Cartilage regeneration and repair mechanisms

• Age-related changes in cartilage tissue

• Chondroprotective mechanisms in inflammatory models

This compound is strictly supplied as a lyophilized powder for reconstitution and is for research purposes only. Researchers buy Cartalax 20mg USA for fundamental investigations into cartilage biology, chondrocyte function, and connective tissue regeneration.

Product Specifications Table

How It Works 

Cartalax is a tissue-specific peptide bioregulator designed for cartilage and connective tissue research. The proposed mechanism involves direct interaction with nuclear chromatin and modulation of chondrocyte gene expression. The bioregulator paradigm differs significantly from classical growth factor and cytokine signaling.

1. The Cartilage-Specific Bioregulator Paradigm:

Peptide bioregulators are short-chain oligopeptides (2-4 amino acids) that differ from classical signaling molecules in several key ways:

2. Proposed Molecular Mechanisms in Chondrocytes:

A. Chromatin Interaction and Nuclear Transport:
Due to their small size (<1000 Da), oligopeptide bioregulators may cross both the cell membrane (via paracellular or active transport mechanisms including PEPT1/PEPT2 oligopeptide transporters) and the nuclear membrane (via nuclear pore complexes, which permit passive diffusion of molecules <40 kDa). Once in the nucleus, Cartalax components may:

• Directly interact with specific DNA sequences (putative bioregulator response elements)

• Bind to transcription factors or chromatin-associated proteins

• Influence nucleosome positioning and chromatin accessibility at cartilage-specific genes

• Modulate epigenetic marks relevant to chondrocyte differentiation including DNA methylation and histone acetylation

B. Cartilage-Specific Gene Expression Modulation:
Cartalax is designed to influence genes critical for cartilage structure and function:

C. Chondrocyte Phenotype Maintenance:
In monolayer culture, primary chondrocytes rapidly dedifferentiate to a fibroblast-like phenotype characterized by:

• Loss of cartilage-specific markers: Decreased COL2A1, ACAN, SOX9 expression

• Gain of fibroblast markers: Increased COL1A1, COL3A1 expression

• Morphological changes: Change from polygonal to spindle-shaped
  Cartalax may help maintain the differentiated chondrocyte phenotype in research models through sustained expression of SOX9 and cartilage matrix genes.

3. Comparison to Other Cartilage Research Compounds:

4. Research Applications in Cartilage Biology:

Cartalax is specifically used in research contexts involving:

• Chondrocyte differentiation: Studying factors that promote or maintain the differentiated chondrocyte phenotype

• Cartilage matrix synthesis: Investigating ECM production, assembly, and turnover

• Osteoarthritis models: Researching protective or regenerative effects in cartilage degradation models (IL-1β or TNF-α stimulated)

• Cartilage regeneration: Studying repair mechanisms in cartilage explants and scaffold-based systems

• Age-related cartilage changes: Researching bioregulator effects on aged chondrocytes and senescent phenotypes

• Comparative bioregulator studies: Understanding tissue specificity by comparing Cartalax to other bioregulators (Epithalon, Livagen, Ovagen)

• Post-traumatic OA models: Investigating bioregulator effects following mechanical injury to cartilage explants

5. Distinction from Growth Factor-Based Approaches:

📦 Storage Instructions 

Proper storage of Cartalax 20mg (Bioregulator) ensures maximum stability for your cartilage research:

1. Store at -20°C for long-term stability:

Unopened vials remain stable for 24 months in a non-frost-free laboratory freezer. Do NOT store in a self-defrosting (auto-defrost) freezer as temperature fluctuations during defrost cycles cause peptide degradation. Use a laboratory freezer with constant temperature monitoring.

2. Refrigerate after reconstitution (2–8°C):

Once dissolved in bacteriostatic water, sterile PBS, or cell culture media, store at 2-8°C (standard laboratory refrigerator). Use within 14 days for bacteriostatic water formulations or 21 days if preservative-containing vehicles are used. Do NOT freeze reconstituted solutions as ice crystals can damage oligopeptide structure.

3. Avoid repeated freeze-thaw cycles:

Aliquot reconstituted peptide into single-use portions (e.g., 50-100 µL in sterile PCR tubes) before freezing if long-term storage after reconstitution is necessary. Each aliquot should undergo no more than ONE freeze-thaw cycle.

4. Protect from light and moisture:

Store original lyophilized vials in the provided amber container or foil-wrapped box. Peptide bioregulators are photosensitive – prolonged light exposure causes degradation. Use amber glass vials for working solutions.

5. Maintain sterile conditions:

Always use a sterile syringe, 0.22 µm filter, and laminar flow hood when piercing the septum. Contamination leads to endotoxin buildup (>10 EU/mg) which activates TLR4 pathways and confounds chondrocyte signaling studies.

6. Desiccate lyophilized powder:

Store unopened vials with the provided desiccant pack. Open vials only in low-humidity environments (<30% RH) to prevent moisture absorption, which causes peptide aggregation.

Stability timeline:

• Lyophilized at -20°C: 24 months (≥98% purity)

• Lyophilized at 2-8°C: 6 months (≥95% purity)

• Lyophilized at room temperature: 14 days (≥90% purity)

• Reconstituted at 2-8°C: 14-21 days (≥90% purity)

• Reconstituted at room temperature: 24-48 hours

For chondrocyte culture studies: Prepare fresh working solutions from lyophilized aliquots every 7-10 days for optimal activity in long-term differentiation or phenotype maintenance studies (which often require 14-21 day culture periods). Discard any solution that appears turbid.

🧪 How It Is Used 

Reconstitution Protocol for In Vitro Studies

1. Centrifuge the sealed vial:

• Centrifuge at 3,000 RPM for 2 minutes to pull lyophilized powder to the bottom. This prevents loss when opening and ensures complete recovery of the 20mg dose.

2. Prepare sterile vehicle:

• For cell culture (chondrocyte studies): Use sterile, endotoxin-free PBS or serum-free DMEM/F12 (chondrocyte-optimized media).

• For cartilage explants: Reconstitute in sterile PBS or serum-free DMEM.

• For stock solutions (higher concentration): Use sterile water (up to 10 mg/mL).

3. Add vehicle to achieve desired stock concentration:

• Standard stock: 1 mg/mL (add 20 mL vehicle to 20mg vial)

• Concentrated stock (for long-term storage): 5-10 mg/mL (add 2-4 mL vehicle)

• Working solution: Dilute stock 1:10 to 1:100 in culture media (final 10-100 µg/mL)

4. Swirl gently:
Do NOT vortex or shake vigorously as this causes foaming and may denature oligopeptide structure.

5. Allow 2-3 minutes for complete dissolution:
Solution should be clear and colorless. Any turbidity or precipitation indicates aggregation or contamination – do not use.

We do not use economy ground shipping (UPS Ground, FedEx Ground) for domestic orders – only expedited air services to ensure peptide integrity.

Is your Cartalax lab tested?

Absolutely – and we provide full transparency. Each batch undergoes independent third-party testing by ISO/IEC 17025:2017 accredited laboratories (contract labs in San Diego, CA and Research Triangle Park, NC). Testing includes:

• HPLC-MS (High Performance Liquid Chromatography – Mass Spectrometry): Minimum 99% purity, full chromatogram provided.

• Amino Acid Analysis (AAA): Peptide composition verification (oligopeptide fingerprint).

• Endotoxin testing: LAL assay, <1.0 EU/mg (essential for cell culture work).

• Residual solvent analysis: Meets ICH Q3C guidelines (Class 1, 2, 3 solvents).

• Heavy metals: ICP-MS, <20 ppm (lead, arsenic, mercury, cadmium).

• Bioburden: <100 CFU/vial (sterility for in vitro use).

• Mass confirmation: ESI-MS (oligopeptide fingerprint).

You can view the Certificate of Analysis (CoA) in two ways: (1) Scan the QR code on your vial’s box for direct portal access, or (2) Enter the batch number on our “Product Verification” page. All CoAs are valid for 24 months from the date of synthesis.

How is Cartalax stored for long-term stability?

Long-term storage (lyophilized powder): Store at -20°C (±5°C) in a non-frost-free (manual defrost) laboratory freezer. Do NOT use a self-defrosting (auto-defrost) freezer as temperature fluctuations during defrost cycles (typically every 6-12 hours) cause peptide aggregation. Unopened vials are stable for 24 months under these conditions.

Short-term storage (up to 2 weeks): Lyophilized vials can be stored at 2-8°C (standard laboratory refrigerator) if used within 14 days. Purity remains ≥95%.

After reconstitution: Store at 2-8°C (refrigerate). Use within 14 days if reconstituted in bacteriostatic water or sterile PBS. Use within 21 days if reconstituted in bacteriostatic water containing 0.9% benzyl alcohol preservative. Do NOT freeze reconstituted solutions – ice crystals damage the oligopeptide structure and cause aggregation.

Handling tips: Always allow frozen vials to come to room temperature (20-25°C for 15 minutes) before opening to prevent condensation. Reconstituted solutions should be aliquoted (single-use portions) if multiple uses are needed over weeks. Each aliquot should undergo only one freeze-thaw cycle maximum.

How is Cartalax used in research?

Reconstitution protocol:

1. Centrifuge sealed vial at 3,000 RPM for 2 minutes to pull powder to bottom.

2. Under laminar flow hood, sterilize septum with 70% isopropyl alcohol.

3. Add 20 mL sterile PBS or bacteriostatic water for 1 mg/mL stock.

4. Swirl gently – do NOT vortex or shake vigorously.

5. Allow 2-3 minutes for complete dissolution (clear, colorless solution).

In vitro applications (chondrocyte and cartilage research):

• Cell types: Primary chondrocytes (human, bovine, porcine, equine, murine), ATDC5 cell line, primary human OA chondrocytes, mesenchymal stem cells (chondrogenic differentiation)

• Culture models: Monolayer culture, high-density pellet culture, alginate beads, micromass culture, scaffold-based 3D culture, cartilage explants

• Concentration range: 0.1-100 µg/mL (concentration optimization recommended)

• Typical concentration: 10-50 µg/mL for most applications

• Treatment duration: 24-96 hours for gene expression; 7-28 days for matrix accumulation and differentiation studies

Key assays:

• Gene expression: qPCR for COL2A1, ACAN, SOX9, MMP-3, MMP-13 (catabolic markers)

• Matrix staining: Safranin O, Alcian Blue, Type II collagen IHC

• sGAG quantification: DMMB assay for proteoglycan content

• Catabolic models: IL-1β (1-10 ng/mL) or TNF-α (10-50 ng/mL) stimulation with/without Cartalax

• 3D culture: Pellet culture (2-5 × 10⁵ cells/pellet, 14-28 days) or alginate beads

• Explants: Articular cartilage explants (3-8 mm punches, 7-28 days)

Strictly for research purposes only – not for human diagnostic, therapeutic, or clinical use.

Can Cartalax be stacked with other peptides?

Yes – stacking is common in cartilage and osteoarthritis research for investigating complementary mechanisms. Synergistic combinations include:

Cartalax + TGF-β1 (Chondrogenic Growth Factor): TGF-β1 induces chondrogenesis and matrix synthesis via SMAD signaling. Cartalax may complement this through nuclear pathways. Used in MSC chondrogenic differentiation and chondrocyte phenotype maintenance studies. Typical ratio: Cartalax 10-50 µg/mL + TGF-β1 1-10 ng/mL.

Cartalax + IGF-1 (Insulin-like Growth Factor-1): IGF-1 promotes ECM synthesis (proteoglycan and collagen) and chondrocyte survival via PI3K/Akt. Cartalax affects anabolic pathways through different mechanisms. Used in osteoarthritic chondrocyte studies and matrix accumulation assays. Typical ratio: Cartalax 10-50 µg/mL + IGF-1 10-100 ng/mL.

Cartalax + BPC-157 (Tissue Repair Peptide): BPC-157 is studied in tendon, ligament, and muscle healing with effects on angiogenesis. Combined with cartilage-specific Cartalax for multi-tissue connective tissue regeneration research. Typical ratio: Cartalax 10-50 µg/mL + BPC-157 10-50 µg/mL.

Cartalax + GHK-Cu (Copper Peptide): GHK-Cu affects ECM remodeling and collagen synthesis. Combined with Cartalax (chondrocyte-specific) for comparative connective tissue biology across cell types. Typical ratio: Cartalax 10-50 µg/mL + GHK-Cu 1-10 µM.

Cartalax + IL-1β (Catabolic Stimulus) – Protective Effects Study: IL-1β induces cartilage degradation (MMPs, aggrecan loss, NF-κB). Cartalax is tested for chondroprotective effects, mimicking DMOAD (Disease-Modifying Osteoarthritis Drug) research. Typical ratio: Cartalax 25-100 µg/mL + IL-1β 1-10 ng/mL.

Cartalax + Epithalon (Pineal Bioregulator): Both are peptide bioregulators with different tissue specificity (cartilage vs pineal). Comparative studies investigate bioregulator tissue specificity vs universal mechanisms. Typical ratio: Cartalax 10-50 µg/mL, Epithalon 10-50 µg/mL (compare on chondrocytes vs other cell types).

Cartalax + MSCs (Mesenchymal Stem Cells) + TGF-β3: Cartalax effects on MSC chondrogenic differentiation alone or with TGF-β3 (standard chondrogenic inducer). Used in cartilage tissue engineering and regenerative medicine research. Typical ratio: Cartalax 10-100 µg/mL + TGF-β3 10 ng/mL in chondrogenic differentiation medium.

Cross-sell opportunity: Add TGF-β1 10µg, IGF-1 100µg, BPC-157 5mg, GHK-Cu 200mg, or Epithalon 50mg to your cart when you buy Cartalax 20mg USA. Bulk stacking discounts: 15% off for 3+ peptides, 25% off for 5+ peptides.
