Description
IGF-1 LR3 is a modified synthetic analogue of Insulin-Like Growth Factor 1 (IGF-1) developed for research use, engineered to provide extended stability and prolonged activity compared to native IGF-1. The “LR3” designation refers to structural modifications that include an amino acid substitution and an extended peptide chain, which together are designed to reduce degradation and alter binding behavior in biological systems.
This peptide is widely researched for its role in cellular growth signaling, particularly pathways related to cell proliferation, differentiation, and tissue development. IGF-1 LR3 is studied for its ability to interact with the IGF-1 receptor (IGF-1R) and influence downstream signaling cascades, including pathways commonly linked to cellular metabolism and growth regulation.
One key research feature of IGF-1 LR3 is its reduced affinity for certain IGF binding proteins (IGFBPs) compared to regular IGF-1, which may increase its availability in experimental models and contribute to its longer-lasting response profile.
Research applications include investigation of:
-
IGF-1 receptor signaling dynamics
-
Cell growth and regeneration mechanisms
-
Muscle biology and tissue development research
-
Metabolic signaling pathways influenced by IGF activity
For research use only.
- guaranteed purity
- third-party tested
- sterilized vials
