Description

Tyrosine Kinase ErbB3 Human Recombinant (HER3) produced in E.Coli is a single, non-glycosylated polypeptide consisting of several epitopes of extracellular domain of human Erb-b3, and having a total molecular mass of approximately 12.0 kDa.The ErbB3 is pu

Protein Background

ErbB3, also called Her3 (human epidermal growth factor receptor 3), is a type I membrane glycoprotein that is a member of the ErbB family of tyrosine kinase receptors. ErbB family members serve as receptors for the epidermal growth factor (EGF) family of

Expression host

Escherichia Coli.

Synonyms

Receptor tyrosine-protein kinase erbB-3, EC 2.7.10.1, c-erbB3, Tyrosine kinase-type cell surface receptor HER3, ErbB3, HER3.

Reagent Appearance

A white semitransparent suspension at a concentration of 1 mg/ml.

Stability

ErbB3 although stable at 4°C for 1 week, should be stored below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.

Biological Activity

Measured by its ability to postpone tumor emerge time of spontaneous breast cancer in FVB/N transgenic mice and inhibit the development of tumor, effectively inhibit the growth of in situ transplanted breast cancer in FVB/N transgenic mice.
