IGF-1 LR3
IGF-1 LR3 is a recombinant 83-residue analogue of insulin-like growth factor 1 with a 13-residue N-terminal extension and an Arg substitution at position 3, which reduces binding to IGF-binding proteins. It is widely used in cell culture and has been studied in experimental models of IGF-1 receptor signaling and cell proliferation.
For in-vitro laboratory research only. Not for human or veterinary use.
