IGF-1 LR3 1 mg

IGF-1 LR3 is a synthetic, modified version of insulin-like growth factor 1, built as an 83-amino-acid chain with an extra section added to one end and a single swapped building block. It is best known in research for how it activates the IGF-1 receptor, and what sets it apart is that it largely sidesteps the binding proteins that normally hold IGF-1 in check.

It rests on an established research base, including early work characterizing how this kind of analog behaves with its binding proteins (Tomas et al., 1992, Biochemical Journal). That is why it often turns up as a reference compound in growth-factor signaling studies.
