IGF-1 LR3 1mg For Sale

IGF-1 LR3 1mg For Sale. IGF-1 LR3 is a research peptide based on human insulin-like growth factor-1 that laboratories use to study growth-factor signalling, protein synthesis, and metabolic pathways in controlled in-vitro systems.

IGF-1 LR3 (Long R3 Insulin-Like Growth Factor-1)

This Long R3 variant includes a 13-amino-acid extension and an arginine substitution at position 3. These sequence changes reduce binding to IGF-binding proteins (IGFBPs) and support sustained availability in experimental models.
For laboratory research only. Not for human use.

Handling & storage

1. Storage (dry): Keep vials protected from light and moisture.
2. Reconstitution: Bring vial and diluent to room temperature. Reconstitute with
   Bacteriostatic Water 10 ml. Swirl gently — do not vortex.
3. After reconstitution: Store at 2–8 °C, protect from light, use aliquots to reduce handling, and avoid repeated temperature cycling.
4. Compatibility: Use only within research protocols that follow your lab’s SOPs and local regulations.

About IGF-1 LR3 in research

IGF-1 LR3 retains receptor-binding characteristics of native IGF-1 while its sequence modifications help sustain activity in vitro by limiting IGFBP interactions. Consequently, researchers use it to probe cell growth and differentiation, protein synthesis, and glucose-metabolism pathways in non-clinical models.

Synthesis & quality

Manufactured via controlled, validated peptide-synthesis processes to deliver high purity and lot-to-lot consistency. Each batch undergoes identity, purity, and appearance checks before release.

Legal & safety

XL Peptides supplies materials strictly for laboratory research. Products are not medications, foods, supplements, or cosmetics; not for human or veterinary use. By purchasing, you confirm you are a qualified researcher and will handle the material in line with your institution’s policies and applicable laws.
