IGF-1 LR3 research material
IGF-1 LR3 (Long R3 IGF-1) is an 83-residue analog of insulin-like growth factor 1. It differs from the 70-residue native IGF-1 in two ways: a 13-residue extension (MFPAMPLSSLFVN) at the N-terminus, and arginine in place of glutamate at position 3 of the IGF-1 sequence, which is the "R3" in the name. Both changes greatly reduce binding to IGF-binding proteins while leaving the IGF-1 receptor (IGF1R) binding region intact, which is why the analog is widely used in cell-culture research.
IGF-1 LR3 Labs supplies it as a lyophilized powder in 1 mg vials. Each lot is tested by ILS Laboratories for HPLC purity, identity against a reference standard and net content, with a fentanyl screen, and the certificate is published here before sale through Klow.bio.
