Research Overview

IGF-1 LR3 is a long-acting recombinant analogue of Insulin-Like Growth Factor 1 studied in cell proliferation, differentiation, and signaling research.

IGF-1 LR3 (Long-R3-IGF-1) is a synthetic 83-amino acid analogue of IGF-1 with an arginine substitution and N-terminal extension that reduces IGF binding protein affinity. This modification makes it a valuable research tool for studying IGF-1 receptor signaling, cell proliferation assays, and differentiation cascades in vitro without the confounding influence of IGFBPs. For qualified laboratory research only.
