What Is IGF-1 LR3 1mg?

IGF-1 LR3 1mg (Insulin-like Growth Factor-1 Long Arginine 3) is a synthetic analog of native IGF-1, engineered for enhanced research utility. IGF-1 LR3 features a 13-amino acid extension peptide at the N-terminus (MFPAMPLSSL FVNG) and an arginine substitution at position 3 of the native IGF-1 sequence. These modifications significantly reduce binding to IGF-binding proteins (IGFBPs 1-6), which normally sequester native IGF-1 and limit its bioavailability. The LR3 modification results in >100-fold reduction in IGFBP binding affinity, allowing extended half-life and enhanced bioactivity in research models. Each 1mg vial contains lyophilized powder requiring reconstitution before laboratory use. This “Receptor Grade” designation indicates ultra-high purity (99%+) specifically optimized for receptor binding studies, cell signaling research, and in vitro assays. IGF-1 LR3 1mg is strictly for research purposes including cell culture, receptor pharmacology, and signal transduction studies.

What Is IGF-1 LR3 1mg Used For (Research Context Only)

In controlled laboratory settings, IGF-1 LR3 1mg is used to investigate:

• IGF-1 receptor (IGF-1R) activation and downstream signaling pathways (PI3K/Akt, MAPK/ERK)

• Cell proliferation, differentiation, and apoptosis mechanisms in multiple cell lines

• Receptor binding affinity and competitive displacement assays

• Neuronal survival, neuroprotection, and synaptic plasticity in cell culture models

• Muscle hypertrophy and protein synthesis pathways in myoblast cultures

• Metabolic regulation, glucose uptake, and insulin signaling cross-talk

• Wound healing and tissue regeneration in in vitro models

• Long-term chronic dosing studies in vivo (extended half-life research)

• Comparative studies between native IGF-1, IGF-1 LR3, and Des(1-3) IGF-1

• Stem cell proliferation and differentiation research

This product is strictly for in vitro and in vivo research use only. It is not for human consumption, medical treatment, or diagnostic use. Receptor Grade ensures minimal interference for ligand-receptor studies.

Product Specifications Table

How It Works (Scientific Explanation)

IGF-1 LR3 1mg is a synthetic analog of Insulin-like Growth Factor-1 engineered for enhanced research utility through reduced IGFBP binding.

Structural Modifications:
Native IGF-1 binds with high affinity to IGFBPs (IGFBP-1 through IGFBP-6), which sequester the peptide and reduce its bioavailability. IGF-1 LR3 incorporates two critical modifications:

1. Arginine substitution at position 3 – Disrupts the IGFBP binding domain

2. 13-amino acid N-terminal extension (MFPAMPLSSL FVNG) – Creates steric hindrance preventing IGFBP interaction

These modifications result in >100-fold reduction in IGFBP binding affinity compared to native IGF-1.

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:

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

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

• mTOR Pathway – Regulates protein translation and cellular growth

Research Advantages of IGF-1 LR3:

The extended half-life and enhanced bioavailability make IGF-1 LR3 particularly valuable for:

• Long-term cell culture studies requiring sustained receptor activation

• In vivo research with reduced dosing frequency

• Studies requiring consistent IGF-1 levels over extended time periods

• Receptor binding assays without BP interference

📦 Storage Instructions

Proper storage ensures peptide stability, research validity, and reproducible results for your IGF-1 LR3 1mg:

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

• 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 – aliquot for multiple uses

• 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

Aliquoting Recommendation for 1mg Vials:

• Reconstitute 1mg in 1mL of 10-20mM acetic acid = 1mg/mL (1000mcg/mL) concentration

• Divide into 10 x 0.1mL aliquots (100mcg each) for single-use storage

• Store aliquots at -20°C for up to 6 months

• Avoid refreezing after thawing

🧪 How It Is Used (RESEARCH CONTEXT ONLY)

In a research setting, IGF-1 LR3 1mg is typically reconstituted and used as follows:

Reconstitution Protocol:

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)

3. Gently swirl (do not shake) until completely dissolved – typically 5-10 minutes

4. Allow reconstituted solution to sit for 10-15 minutes at room temperature

5. For cell culture, dilute further in sterile PBS or culture media (avoid neutral pH shock)

6. Use immediately or store at 2-8°C for up to 30 days

Typical Research Applications:

All handling must be performed in a controlled laboratory environment with appropriate personal protective equipment (PPE) and safety protocols.

Strictly for research purposes only. Not for human use.
