Human ErbB2/Her2 (Research Grade Trastuzumab Biosimilar) Antibody Summary

Species Reactivity
Human
Specificity
Detects human ErbB2/Her2 in direct ELISAs. This non-therapeutic antibody uses the same variable region sequence as the therapeutic antibody Trastuzumab. This product is for research use only.
Source
Recombinant Monoclonal Human IgG1 Clone # Hu5
Purification
Protein A or G purified from cell culture supernatant
Immunogen
Human ErbB2/Her2
Formulation
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
Label
Unconjugated

Applications

Recommended Concentration
Sample
Flow Cytometry
0.25 µg/106 cells
See below
CyTOF-ready
Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.
 
Inhibition of Cell Growth
Measured by its ability to inhibit proliferation in the SK‑BR‑3 human breast cancer cell line. Brodowicz, T. et al. (1997) Int. J. Cancer 73:875. The ED50 for this effect is typically 15-75 ng/mL.
 

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Background: ErbB2/Her2

Trastuzumab is a biosimilar directed against the extracellular domain of Her2 (ErbB2). This product constitutes the immunogen used for the anti-Idiotype catalog numbers MAB9547 and MAB95471. The biotinylated antibody (catalog number FAB9589B) can be used in flow cytometry or various assay formats to measure Her2 expression and can be detected by conjugated streptavidin.
