IGF-1 LR3 is a long-acting analog of insulin-like growth factor 1 with an arginine substitution and 13 amino acid extension, studied in cell growth, proliferation, and metabolic signaling research.
IGF-1 LR3 is a modified research analog of insulin-like growth factor 1 featuring an arginine substitution at position 3 and an N-terminal 13 amino acid extension. These changes sharply reduce binding to IGF-binding proteins, extending its active life and making it a common tool in cell culture work examining proliferation, differentiation, and IGF-1 receptor signaling.
Research Applications
Handling & Storage
Supplied as a lyophilized powder. Store sealed vials in a cool, dry place away from light; refrigerate after reconstitution with bacteriostatic water and avoid repeated freeze-thaw cycles.
This compound is intended for in-vitro research and laboratory use only. Not for human consumption.
