NewEast Biosciences pioneered the research and development of the antibodies for GTPases and mutated Oncogene ten years ago. GTPases involve (1) signal transduction in response to activation of cell surface receptors, including transmembrane receptors such as those mediating taste, smell and vision, (2) protein biosynthesis at the ribosome, (3) regulation of cell differentiation, proliferation, division and movement, (4) translocation of proteins through membranes, (5) transport of vesicles within the cell, and vesicle-mediated secretion and uptake, through GTPase control of vesicle coat assembly. An oncogene is a gene that has the potential to cause cancer.
We offer three unique categories of antibodies, which (1) recognize only the active configuration of GTPase (not the inactive one), (2) mutated Oncogene (not mild type) and (3) have super affinity for cAMP and cGMP (no acetylation required). We have over one thousand peer reviewed articles cited our products.

ErbB2 Polyclonal Antibody
Cat. #: 21202 |
Gene Symbol: ERBB2/HER2/Neu |
Description: Anti-ErbB2 Rabbit Polyclonal Antibody |
Background: The ErbB family is composed of four plasma membrane-bound receptor tyrosine kinases. Amplification or over-expression of the ERBB2 gene occurs in approximately 30% of breast cancers. HER2 is encoded by ERBB2, a known proto-oncogene located at the long arm of human chromosome 17(17q21-q22). HER2 proteins have been shown to form clusters in cell membranes that may play a role in tumorigenesis. |
Immunogen: A synthetic peptide from the central of ErbB2 protein. |

Western blot: Western blot analysis of ErbB2 protein. Purified full length His-tagged ErbB2 protein (Cat. #10208) was blotted with Anti-ErbB2 rabbit polyclonal antibody (Cat. #21202). Immunohistochemical analysis of paraffin-embedded human breast cancer tissue with Anti-ErbB2 polyclonal antibody (Cat. #21202). Tissue samples were fixed with formaldehyde and blocked with 1% serum for 15 min at 37 °C. Antigen retrieval was by heat mediation in citrate buffer (pH6). Samples were then incubated with primary antibody (1:50 dilution) overnight at 4 °C. A HRP-conjugated Goat anti-Rabbit IgG (1:50) was used as secondary antibody. |
