GRB2, 1-217 aa, Human, His-tagged, Recombinant, E.coli

Growth factor receptor-bound protein 2 also known as Grb2 is an adaptor protein that provides a critical link between cell surface growth factor receptors and the Ras signaling pathway. GRB2 is widely expressed and also binds the epidermal growth factor receptor and contains one SH2 domain and two SH3 domains. Grb2 is composed of an SH2 domain flanked on each side by an SH3 domain. Inhibition of Grb2 function impairs developmental processes in various organisms and blocks transformation and proliferation of various cell types. Recombinant human GRB2 protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography.

Can be stored at +4C short term (1-2 weeks). For long term storage, aliquot and store at -20C or -70C. Avoid repeated freezing and thawing cycles.
