ErbB2/Her2 Antibody (PD00-53)

Immunohistochemistry: ErbB2/Her2 Antibody (PD00-53) [NBP3-32422] - Immunohistochemical analysis of paraffin-embedded human breast carcinoma tissue with Rabbit anti-ErbB2/Her2 antibody (NBP3-32422) at 1/2,000 dilution. The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (NBP3-32422) at 1/2,000 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Immunocytochemistry/ Immunofluorescence: ErbB2/Her2 Antibody (PD00-53) [NBP3-32422] - Immunocytochemistry analysis of MCF-7 cells labeling ErbB2/Her2 with Rabbit anti-ErbB2/Her2 antibody (NBP3-32422) at 1/50 dilution. Cells were fixed in 4% paraformaldehyde for 10 minutes at 37 ℃, permeabilized with 0.05% Triton X-100 in PBS for 20 minutes, and then blocked with 2% negative goat serum for 30 minutes at room temperature. Cells were then incubated with Rabbit anti-ErbB2/Her2 antibody (NBP3-32422) at 1/50 dilution in 2% negative goat serum overnight at 4 ℃. Goat Anti-Rabbit IgG H&L (iFluor™ 488) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. Nuclear DNA was labelled in blue with DAPI.

Flow Cytometry: ErbB2/Her2 Antibody (PD00-53) [NBP3-32422] - Flow cytometric analysis of SK-Br-3 cells labeling ErbB2/Her2. Cells were fixed and permeabilized. Then stained with the primary antibody (NBP3-32422, 1μg/mL) (red) compared with Rabbit IgG Isotype Control (green). After incubation of the primary antibody at +4℃ for an hour, the cells were stained with a iFluor™ 488 conjugate-Goat anti-Rabbit IgG Secondary antibody at 1/1,000 dilution for 30 minutes at +4℃. Unlabelled sample was used as a control (cells without incubation with primary antibody; black).

Background

ErbB2/HER2 is one of the four members of the ErbB receptor family of transmembrane receptor-like tyrosine kinases (1). The kinase activity of ErbB2 can be activated without ligand if it is overexpressed, and by association with other ErbB proteins (2). Overexpression of ErbB2 is detected in almost 40% of human breast cancers (3). Binding of c-Cbl ubiquitin ligase to Tyr1112 of ErbB2 leads to poly-ubiquitination of ErbB2 and enhances its degradation (4). ErbB2 is one of the major targets for the treatment of breast cancer and other carcinomas.
