Description

S961 is an high-affinity and selective insulin receptor (IR) antagonist with IC50s of 0.048, 0.027, and 630 nM for HIR-A, HIR-B, and human insulin-like growth factor I receptor (HIGF-IR) in SPA-assay, respectively[1].

In Vitro

S961 also shows high-affinity to Rat IR and Pig IR with IC50s of 0.056 nM and 0.084 nM in PEG-assay, respectively[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
