Catalog #: PKA-342
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 purified by proprietary chromatographic techniques.
Synonyms:
Receptor tyrosine-protein kinase erbB-3, EC 2.7.10.1, c-erbB3, Tyrosine kinase-type cell surface receptor HER3, ErbB3, HER3.
Source:
Escherichia Coli.
Purity:
Greater than 95.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
Formulation:
Each mg protein contains 1 mg aluminum hydroxide 10mM arginine, 10mM sodium chloride, 20mM sodium phosphate buffer and 5mM potassium phosphate.
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.
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.
Physical Appearance:
A white semitransparent suspension at a concentration of 1 mg/ml.
Dilution:
It is recommended that sterile phosphate-buffered saline containing 1mg aluminum hydroxide be added to the vial to prepare a stock solution.
