Highlighted Antibody - HER2 (ERBB2) Clone BSR44
|
HER2/ERBB2, is a member of the epidermal growth factor (EGF) receptor family of receptor tyrosine kinases. Amplification and/or overexpression of this gene has been reported in numerous cancers, including breast and gastric tumors. Immunohistochemical staining of HER-2 protein is graded as 0/1+, 2+ and 3+.
This antibody provides truly optimal staining and as with all our antibodies we provide a 100% guarantee, so trying it really is risk free.
