HER2 Antibody (RM228)

Catalog #CA015



HER2 is a member of the epidermal growth factor (EGF) receptor family of receptor tyrosine kinases. This protein has no ligand binding domain of its own and therefore cannot bind growth factors. However, it does bind tightly to other ligand-bound EGF receptor family members to form a heterodimer, stabilizing ligand binding and enhancing kinase-mediated activation of downstream signaling pathways, such as those involving mitogen-activated protein kinase and phosphatidylinositol-3 kinase. Amplification and/or overexpression of this gene has been reported in numerous cancers, including breast and ovarian tumors. Alternative splicing results in several additional transcript variants, some encoding different isoforms and others that have not been fully characterized.



IHC staining of formalin fixed and paraffin embedded human breast cancer tissue sections, using HER2 antibody (clone RM228).

Western Blot analysis of MCF-7, PC3, Jurkat, and A375 cell lysates using HER2 antibody (clone RM228), showed a band of HER2 expressed only in MCF-7 cells.
