Product Title
High Purity IGF‑1 LR3 (Long R³ IGF‑1) Lyophilized Powder, CAS 946870‑92‑4, Purity ≥99% HPLC
Product Detailed Description
supplies premium grade IGF‑1 LR3 (Long Arginine 3 Insulin‑like Growth Factor‑1), a genetically engineered analog of human Insulin‑like Growth Factor‑1. This recombinant polypeptide is manufactured under standardized production procedures, with confirmed purity higher than 99% tested by High‑Performance Liquid Chromatography (HPLC). All batches are accompanied by official Certificate of Analysis (COA) to support your research projects.
Distinguished from native IGF‑1, IGF‑1 LR3 contains two core structural modifications: an extra 13‑amino‑acid extension on the N‑terminus and a glutamate‑to‑arginine substitution at position 3. These adjustments greatly reduce its binding affinity with IGF binding proteins (IGFBPs) existing in biological systems. Native IGF‑1 is mostly locked by IGFBPs and loses biological activity rapidly. In contrast, IGF‑1 LR3 maintains stable free active status and possesses an extended biological half‑life reaching 20–30 hours, which makes it far more effective for long‑term cell incubation and animal model studies.

Our IGF‑1 LR3 appears as white to off‑white fluffy lyophilized powder. The raw material dissolves easily in sterile water or bacteriostatic water. After reconstitution, the solution remains clear without visible particles or sediment. Strict internal quality control standards are implemented during production. We control endotoxin level ≤10 EU/mg, residual moisture ≤5.0%, heavy metal contents under 10 ppm to eliminate extra interference to cell and animal experiments.
IGF‑1 LR3 activates the IGF‑1 receptor and regulates two classic downstream signaling pathways: PI3K/Akt/mTOR and MAPK/ERK. Within research environments, it is widely adopted for multiple research directions. In cell culture systems, it facilitates cell proliferation, inhibits cell apoptosis, and supports the cultivation of muscle satellite cells, stem cells, chondrocytes and osteoblasts. For animal laboratory models, researchers utilize IGF‑1 LR3 to carry out studies focused on tissue regeneration, skeletal development, muscle growth mechanisms, nerve cell protection and wound recovery mechanism exploration.

Proper storage and operation are essential to preserve peptide activity. Undissolved lyophilized IGF‑1 LR3 should be sealed and stored at -20℃ under dark and dry conditions, avoiding repeated freeze‑thaw cycles. Under recommended storage conditions, the shelf life of dry powder reaches 24 months. Once reconstituted, the solution needs to be kept at 2–8℃ and consumed within 28 days to prevent activity degradation and microbial contamination.

offers flexible packaging solutions to satisfy diverse research demands. Standard specifications include 0. 1mg, 1mg, sealed vial packaging. Customized bulk packaging is available upon customer request. Every package is tightly sealed to avoid moisture and oxidation during international transportation. We support flexible order quantities and stable continuous supply for laboratories, biotech research institutions and research raw material distributors worldwide.
We sincerely remind all partners of the critical usage limitation: IGF‑1 LR3 is exclusively for scientific research use only. This product is not approved for human clinical application, diagnosis or any form of human administration. It cannot be used as pharmaceutical raw material for human medication. Customers are obligated to follow local laws and customs regulations for import, transportation and utilization of research biochemical reagents.
