Synthetic insulin-like growth factor 1 (IGF-1) analogue peptide for in vitro and laboratory research

Description

Euro-Gen IGF1-LR3, 1mg is a research-grade peptide product supplied by Express Peptides under the Euro-Gen brand. It contains 1 mg of IGF-1 LR3 (Long R3 insulin-like growth factor 1), a synthetic analogue of human insulin-like growth factor 1 engineered to have a longer duration of action and increased potency compared to native IGF-1. The Express Peptides product summary describes IGF-1 LR3 as a synthetic form of Insulin-like Growth Factor 1 with an altered structure that allows it to remain active for longer, mimicking natural IGF-1 while being designed to be more potent and longer-acting. Research focuses on its potential to enhance muscle growth, improve recovery and aid in fat loss by promoting cellular growth and regeneration. The Euro-Gen IGF1-LR3, 1mg vial is marketed exclusively for in vitro testing and laboratory research, with prominent statements that it is for research use only, must not be introduced into humans or animals, and is not a drug, food or cosmetic. Express Peptides indicates that its peptides are manufactured in the UK to a minimum purity of greater than 99% and are subject to independent third-party laboratory testing, with Certificates of Analysis available on request.

Composition

  • Active substance: IGF-1 LR3 (Long R3 insulin-like growth factor 1), a synthetic analogue of human insulin-like growth factor 1 (IGF-1)
  • IGF-1 LR3 is an 83-amino-acid single-chain polypeptide analogue of human IGF-1 that differs from native IGF-1 by having an arginine instead of glutamic acid at the third amino acid position ("arginine 3") and an additional 13 amino acids at the N-terminus, commonly described as the sequence MFPAMPLSSLFVNG followed by the native IGF-1 sequence
  • Representative amino acid sequence for human IGF-1 LR3 from recombinant protein datasheets: MFPAMPLSSLFVNGPRTLCGAELVDALQFVCGDRGFYFNKPTGYGSSSRRAPQTGIVDECCFRSCDLRRLEMYCAPLKPAKSA (83 amino acids)
  • Commonly reported molecular formula for IGF-1 LR3 in research peptide catalogues: approximately C400H625N111O115S9, corresponding to a polypeptide of about 9.1–9.2 kDa molecular weight depending on exact counter-ion and hydration state
  • The Euro-Gen IGF1-LR3, 1mg product contains 1 mg of lyophilised IGF-1 LR3 peptide per vial as indicated by the product name; no excipients, stabilisers, preservatives or buffer components are specified in publicly available information for this specific product
  • Express Peptides states that all of its peptides have a minimum purity of >99% and undergo independent third-party laboratory testing, but lot-specific Certificate of Analysis data (such as exact purity percentage, residual solvents, and identity confirmation methods) for Euro-Gen IGF1-LR3, 1mg are not publicly listed and are available only on request
