🔬 Why Researchers Study IGF‑1 LR3

1. Increased stability in vitro

The structural modifications make IGF‑1 LR3 more resistant to degradation, allowing researchers to observe longer‑lasting signalling effects.

2. Reduced IGFBP binding

Native IGF‑1 binds strongly to IGFBPs, which restrict its activity. IGF‑1 LR3 binds far less, making it easier to study IGF‑1 receptor signalling directly.

3. Enhanced potency in cell‑based assays

Because it remains active longer and binds more freely to receptors, IGF‑1 LR3 is often used in:

• growth‑factor pathway research

• cell‑proliferation studies

• metabolic signalling experiments

4. Clearer modelling of IGF‑1 receptor pathways

Its stability and reduced binding interference make it a useful tool for studying:

• PI3K/Akt signalling

• MAPK/ERK pathways

• cellular growth and differentiation mechanisms.

Reconstitute with BAC's Water Only
When reconstituting peptides, it is crucial to use bacteriostatic water (BAC) to ensure sterility and safety.

BAC water contains 0.9% Benzyl Alcohol and is bacteria-proof, making it the preferred choice for reconstitution.

This method helps preserve the integrity of the peptide and prevents contamination.

To reconstitute a peptide blend, follow these steps:
Disinfect both vials and the stoppers with alcohol wipes.

Measure the required amount of BAC water based on the dosage.
Mix the peptide powder with the measured BAC water in a sterile syringe.

Inject the solution into the vial and refrigerate at 2–8°C, protected from light.

Use the reconstituted solution within 4 weeks for best potency and safety.
