Growth Factors

IGF-1 LR3 leads this growth factors category, a recombinant Long R3 analogue of insulin-like growth factor 1 in which an arginine substitution and a 13-residue N-terminal extension reduce binding to IGF-binding proteins. This makes it a widely used reagent for in-vitro cell-culture and receptor-signalling research, and the strongest molecular term in the class. IGF-1 and its Long R3 variant are studied across models of cellular proliferation and differentiation.Alongside it sits Follistatin 344 (FS-344), a glycoprotein studied as an antagonist of TGF-beta superfamily ligands such as myostatin and activin. Both are supplied as characterised research reagents for laboratory use. This category features IGF-1 LR3 and Follistatin 344.What is IGF-1 LR3?IGF-1 LR3 is a Long R3 analogue of insulin-like growth factor 1 with reduced binding-protein affinity, supplied as a lyophilised reagent for in-vitro research.How are these stored?Both are supplied lyophilised, kept cold and reconstituted with bacteriostatic water as a handling step for laboratory study.All compounds are supplied for laboratory research use only. Not for human or animal consumption.
