Research Background

Basic IGF-1 has a very short half-life (minutes) because it is quickly neutralized by IGF Binding Proteins (IGFBPs). IGF-1 LR3 contains an Arginine substitution at position 3 and a 13-amino acid extension, preventing this binding. This allows the free peptide to circulate for ~20-30 hours, continuously activating IGF-1 receptors on muscle cells. This activity is researched for its ability to induce the splitting of muscle cells (hyperplasia), creating new fibers rather than just enlarging existing ones.

Scientifically Investigated Applications

Muscle Hyperplasia Models
Cellular Proliferation Assays
Insulin-like Signaling
Tissue Regeneration

Storage & Handling

Peptides are stable at room temperature for up to 30 days. For long-term storage, keep lyophilized peptides at -20°C. Once reconstituted, store at 4°C and use within 14-21 days. Avoid repeated freeze-thaw cycles.
