ErbB2 (HER-2) Antibody (14-9757-82) in WB
Western blot analysis was performed on whole cell extracts (30 µg lysate) of MDA-MB-231 (Lane 1) and SK-BR-3 (Lane 2). The blots were probed with Anti-ErbB2 (HER-2) Monoclonal Antibody (Product # 14-9757-82, 2 µg/mL) and detected by chemiluminescence using Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A28177, 0.25 µg/mL, 1:4000 dilution). A 185 kDa band corresponding to ErbB2 was observed in SK-BR-3 but not in MDA-MB-231, which is a negative cell line for ErbB2.

Product Specific Information
Description: This MJD2 monoclonal antibody reacts with HER-2, the product of the ErbB2 gene and a member of the human epidermal growth factor receptor (EGFR) family. HER-2 is a 185 kDa transmembrane receptor with an extracellular binding domain and an intracellular tyrosine kinase domain. Activation of HER-2 occurs following formation of homodimers or heterodimers with ligand-bound EGFR family members, HER3 or HER4. Overexpression of HER-2 results in auto-phosphorylation and increased proliferation and invasiveness and is associated with subsets of multiple cancer types such as breast, ovarian, cervical, uterine, and gastric. The use of HER-2 targeted agents has been used extensively to treat HER-2-positive breast cancer, but a recent study found that these agents can also block the proliferation of breast cancer stem cells found in HER-2-negative patients and suggests the importance of HER-2 as a target for multiple types of breast cancer. The MJD2 antibody recognizes the extracellular domain of HER-2 but at an epitope distinct from that recognized by the 4D5 (Herceptin) and SP3 monoclonal antibodies.
Applications Reported: This MJD2 antibody has been reported for use in western blotting, immunohistochemical staining of formalin-fixed paraffin embedded tissue sections, microscopy, and immunocytochemistry.
Applications Tested: This MJD2 antibody has been tested by immunhistochemistry of formalin-fixed paraffin embedded human tissue using low or high pH antigen retrieval and can be used at less than or equal to 5 µg/mL. This MJD2 antibody has been tested by immunocytochemistry of methanol-fixed and permeabilized human BT474 cells and can be used at less than or equal to 5 µg/mL. This MJD2 antibody has been tested by western blot analysis of reduced human BT474 cell lysate and can be used at less than or equal to 5 µg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
Purity: Greater than 90%, as determined by SDS-PAGE.
Aggregation: Less than 10%, as determined by HPLC.
Filtration: 0.2 µm post-manufacturing filtered.
Target Information
ErbB2 (HER2) is a receptor tyrosine kinase that is overexpressed in some breast tumors. Herceptin, used in treatment of metastatic Her2-positive cancer, is monoclonal antibody targeting this kinase.
