Growth Factor Analog

Growth factor analogs are modified versions of naturally occurring growth factors, engineered for altered receptor binding, enhanced stability, or extended biological activity in research applications. These compounds allow researchers to study growth factor signaling under controlled conditions, with modifications that improve experimental reproducibility compared to native growth factor preparations.

The family includes long-arginine analogs of insulin-like growth factor 1 (such as IGF-1 LR3), where structural modifications dramatically extend half-life by reducing binding to IGF binding proteins. This modification allows researchers to study sustained IGF-1 receptor activation in cellular growth, tissue repair, and longevity signaling models — providing experimental advantages that native IGF-1 preparations cannot match.

Growth factor analogs in our catalog feature IGF-1 LR3 (1mg).

Each compound is supplied as a lyophilized powder, ≥98% purity, with Certificate of Analysis. For laboratory research use only.
