Anti-Human ErbB2 Recombinant Antibody (TAB-005)

CAT#: TAB-005

Recombinant monoclonal antibody to Human ErbB2. The antibody is a monoclonal antibody that interferes with the HER2/neu receptor. Its main use is to treat certain breast cancers.
The HER receptors are proteins that are embedded in the cell membrane and communicate molecular signals from outside the cell (molecules called EGFs) to inside the cell, and turn genes on and off. The HER proteins stimulate cell proliferation. In some cancers, notably certain types of breast cancer, HER2 is over-expressed, and causes cancer cells to reproduce uncontrollably.

  • The ERBB2 antibody has been reported in applications of WB, Inhib, IP, H&E staining, IF, Internalization, ADCC.
    WB: Protein samples lysed in Laemmlli sample buffer and were then boiled for 5 min. Equal quantities of protein lysates were then analyzed on SDS-PAGE and transferred to PVDF membrane. The membranes were blocked with 10% skim milk, incubated with primary antibody in 0.4% skim milk/TBS for 2h, washed with TBST followed by appropriate secondary antibody in 0.4% skim milk/TBS incubation for 1 h. The proteins were visualized using Western lighting plus-ECL reagent in Light-Capture II cooled CCD camera system.
    IF: For confocal microscopic observation, SKBR-3 cells and caveolin-1 transfected SKBR-3 cells were grown on 18 mm cover slips. Cells were then fixed with 4% PFA for 10 min, permeabilized with 0.1% Triton X-100/PBS and blocked with 1% BSA-PBS for 30 min at RT. For caveolin-1 localization, cells were incubated with 1:500 diluted anti-caveolin-1 antibody in 0.25% BSA/PBS for 1 h at RT, followed by staining with Alexa 555 labeled anti-rabbit IgG for 30 min. After wash, the cover slips were mounted with DAPI (Vector Laboratories and observed by confocal microscope IX81 with 60x magnification lens.
    ADCC: Caveolin-1 expressing and wild type SKBR-3 and SKOV-3 cells that had been cultured in 96 well plates were incubated with 1 µM of EC-Fc and Trastuzumab for 4 h at 37˚C.

Breast cancer biomarkers at key points during disease progression
Excellent ErbB2 Antibody
This recombinant antibody (TAB-005) targeting human ErbB2 is a cornerstone of my cancer research. It's a humanized IgG1 antibody expressed in CHO, which is a common and reliable format. The product data lists applications like ELISA, FC, and IF, making it a versatile tool in the lab.
Breast cancer biomarkers at key points during disease progression
High Purity, Multiple Apps
I am impressed by the quality of this antibody. The>95% purity determined by SDS-PAGE is exactly what I look for. I've used it for both Western Blot (WB) and functional studies (FuncS), both of which are listed applications, and it has performed reliably in detecting the ErbB2 target.

Q&As

  1. I'm looking for an antibody for functional studies on ErbB2. Is TAB-005 suitable?

    A: Yes, this antibody (TAB-005) is listed for use in Functional Studies (FuncS). It is a recombinant, humanized IgG1 antibody that targets human ErbB2 (also known as HER2). It is expressed in CHO cells with a purity>95% by SDS-PAGE, making it a high-quality reagent suitable for functional research applications, in addition to ELISA, FC, and IF.

  2. What is the derivation of this anti-ErbB2 antibody?

    A: This is an engineered recombinant antibody. It is specified as a humanized antibody, which typically means the antigen-binding loops from a non-human antibody (like mouse) were grafted onto a human IgG1 framework. This format is often used in research to improve compatibility with human-derived samples or assay components.
