Product Overview
IGF 1 LR3 is a synthetic analog of insulin like growth factor 1 modified for increased stability and biological activity in controlled scientific environments. The Long R3 variant includes an arginine substitution at position 3 and an extended amino acid sequence that reduces affinity for IGF binding proteins and increases receptor availability. Research evaluates its influence on cellular growth, protein synthesis, nutrient uptake, and tissue repair signaling.
Intended Applications
- Cellular growth and regeneration studies
- Myogenesis, protein synthesis, and anabolic pathway models
- Neuroprotection and tissue repair investigations
- Research on glucose metabolism and nutrient transport
Storage and Handling
- Store lyophilized material at minus 20°C in a dry, dark, moisture free environment.
- Reconstitute using bacteriostatic water in sterile laboratory conditions.
- Store reconstituted solution refrigerated at 2 to 8°C.
- Avoid repeated freeze thaw cycles.
