  • Anti Erbb2 V777a Mouse Monoclonal Antibody - USA

    price: contact company for price

    Catalog Number: 26080

    Gene Symbol: ERBB2/HER2/Neu

    Description: Anti-ErbB2 (V777A) mouse monoclonal 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. Mutations of ErbB2 protein, including V777A, have been indicated in human cancers.

    Immunogen: A synthetic peptide surround the 777A codon of ErbB2 protein.

    Tested Applications: ELISA, WB, IF, IHC

    Recommended Dilutions:

    ELISA: 1:500-1:5000

    WB: 1:200-1:2000

    IF: 1:100

    IHC: 1:50-1:100

    Concentration: 0.2 mg/ml

    • Business Description: NewEast Biosciences are specialized in generating protein configuration specific monoclonal antibodies that recognize active (GTP bound) G proteins (including Ras superfamily small GTPases and heterotrimeric G proteins). These unique antibodies do not recognize the inactive (GDP bound) G proteins. These monoclonal antibodies have been successfully used to immunoprecipitate active G proteins from cell lysates, and for immunohistochemical staining of active G proteins in cultured cells or in tissue sections. Hence, these antibodies can be used to study the spatial and temporal dynamics of cellular signaling involving big and small G proteins, the future direction of signal transduction studies.
