What Is IGF-1 LR3 (Receptor Grade) 100mcg x 10 Vials?

IGF-1 LR3 (Receptor Grade) 100mcg x 10 Vials is a bulk research pack containing ten individual vials of synthetic IGF-1 LR3 (Insulin-like Growth Factor-1 Long Arginine 3), each with 100mcg of lyophilized powder. IGF-1 LR3 is a modified analog of native IGF-1, engineered with a 13-amino acid N-terminal extension and an arginine substitution at position 3, which significantly reduces binding to IGF-binding proteins (IGFBPs). The “Receptor Grade” designation indicates ultra-high purity (99%+) specifically optimized for receptor binding studies, cell signaling research, and in vitro assays. The 10-vial bulk configuration allows researchers to use one vial per experiment without repeatedly freeze-thawing a larger quantity, preserving peptide integrity and ensuring reproducible results.

What Is IGF-1 LR3 (Receptor Grade) 100mcg x 10 Vials Used For (Research Context Only)

Product Specifications Table

How It Work

IGF-1 LR3 (Receptor Grade) 100mcg x 10 Vials contains a synthetic analog of Insulin-like Growth Factor-1 engineered for enhanced research utility.

Mechanism of Action:
IGF-1 LR3 exerts its effects primarily through the IGF-1 receptor (IGF-1R), a transmembrane tyrosine kinase receptor structurally similar to the insulin receptor. Upon binding, IGF-1R autophosphorylates and activates downstream signaling cascades:

1. PI3K/Akt Pathway – Promotes cell survival, inhibits apoptosis, stimulates protein synthesis, and regulates glucose metabolism

2. MAPK/ERK Pathway – Drives cell proliferation, differentiation, and gene expression

3. mTOR Pathway – Regulates protein translation and cellular growth

Why LR3 Modification Matters:
Native IGF-1 binds with high affinity to IGFBPs (IGFBP-1 through IGFBP-6), which sequester the peptide and reduce its bioavailability. The LR3 modification introduces:

• Arginine substitution at position 3 – Disrupts the IGFBP binding domain

• 13-amino acid N-terminal extension – Creates steric hindrance preventing IGFBP interaction

These modifications result in >100-fold reduction in IGFBP binding affinity, allowing IGF-1 LR3 to remain bioavailable in research models for extended periods (12-24 hours vs 10-20 minutes for native IGF-1).

Bulk Pack Advantage for Research:
The 10-vial configuration allows researchers to reconstitute one vial at a time, maintaining peptide integrity and enabling:

• Multiple time-point experiments

• Dose-response curves with fresh peptide per concentration

• Technical replicates without freeze-thaw degradation

• Long-term studies with consistent peptide quality across all time points

📦 Storage Instructions

Proper storage ensures peptide stability, research validity, and reproducible results for your IGF-1 LR3 (Receptor Grade) 100mcg x 10 Vials:

• Store at -20°C for long-term stability (lyophilized powder) – up to 24 months for unopened vials

• Store unopened vials in original packaging protected from light

• Refrigerate after reconstitution at 2–8°C – use within 30-60 days depending on buffer

• Never freeze reconstituted IGF-1 LR3 – freezing causes aggregation and activity loss

• Avoid repeated freeze-thaw cycles – use one vial per experiment; discard unused reconstituted peptide

• Protect from light and moisture – keep in original amber vial or foil-wrapped container

• Maintain sterile conditions – use sterile syringes, needles, and laminar flow hood

• Do not vortex or shake vigorously – gentle swirling only to avoid denaturation

• Acidic reconstitution buffer – Use 10-20mM acetic acid (pH 3-4) for optimal stability; neutral pH causes aggregation

Vial Management for Bulk Packs:

• Label each vial with date of receipt

• Store unopened vials in a dedicated -20°C freezer section

• Remove only the vial needed for current experiments

• Never return reconstituted peptide to freezer

🧪 How It Is Used (RESEARCH CONTEXT ONLY)

In a research setting, IGF-1 LR3 (Receptor Grade) 100mcg x 10 Vials is typically reconstituted and used as follows:

Reconstitution Protocol (per 100mcg vial):

1. Briefly centrifuge the vial to collect powder at the bottom

2. Add 0.5-1 mL of 10-20mM acetic acid (or sterile water for immediate use)
