Background: CD20

Rituximab is a biosimilar directed against the extracellular domain of CD20. This product constitutes the immunogen used for the anti-Idiotype catalog number MAB9630. The biotinylated antibody (catalog number FAB9575B) can be used in flow cytometry or various assay format to measure CD20 expression and can be detected by conjugated streptavidin.

FAQs

  1. What is a Biosimilar antibody?

    • A Biosimilar antibody is a non-therpeutic, recombinantly-expressed antibody which has the same sequence as the corresponding therapeutic antibody.  It is for research use only. The nomenclature of the Biosimilar antibody includes the name of the therapeutic antibody.  For example, Catalog # MAB9577 is called Human EGFR (Research Grade CetuxiMab Biosimilar) antibody.

  2. Does this Biosimilar antibody have the same sequence as its corresponding therapeutic antibody? 

    • This Biosimilar antibody has the same variable region sequence as the therapeutic antibody, but the constant region is not the same. It contains a proprietary human IgG constant region.
