IGF-1 DES 1 mg

IGF-1 DES (Des(1-3)IGF-1) is a naturally occurring, endogenous truncated form of IGF-1 lacking the first three N-terminal amino acids. This truncation reduces IGFBP affinity by approximately 10-fold relative to native IGF-1 while modestly increasing IGF-1 receptor binding potency. The shorter half-life and higher local potency of IGF-1 DES make it a useful research tool for studying IGF-1R activation dynamics distinct from the longer-acting IGF-1 LR3 analogue.
