Catalog no. :  RPB04626
DNA sequence encoding extracellular domain of Human HER2 (ERBB2)  to a C-terminal polyHis tag was expressed in CHO cells.

Molecular weight:

Recombinant Human HER2  is a monomer consisting of 640 amino acid residue , and migrates as an approximately 75 kDa protein under reducing conditions in SDS-PAGE.

>95%, as determined by SDS-PAGE

ELISA,WB:  Biotinylated HER2 was designed to be used in single step detection in ELISA ,WB

Endotoxin content was assayed using a LAL gel clot method.
Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).

Recombinant Human HER2 was lyophilized from a 0.2 μm filtered PBS  pH 7.4.

A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.

The lyophilized protein is stable for at least 2 years from date of receipt at -20° C.
Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8° C for one month, or at -20° C for six months, with a carrier protein without detectable loss of activity.

Avoid repeated freeze/thaw cycles.

The epidermal growth factor receptor (EGFR) is a 170,000-kDa trans-membrane glycoprotein involved in signaling pathways affecting cellular growth, differentiation, and proliferation.1 An abnormal expression of the EGFR has been described in many human tumors and implicated in the development and prognosis of malignancies, thus representing not only a possible prognostic markers but primarily a rational molecular target for a new class of anticancer agents
