FAQs

Does this Biosimilar antibody have the same sequence as the therapeutic antibody?
- The Biosimilar antibody has the same variable region and constant region sequence as the therapeutic antibody, except for Catalog numbers MAB9677, MAB9575, MAB9577, MAB9589, and their conjugates. These four antibodies have the same variable region as the Biosimilar, but not the same constant region.
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.
What is the light chain of Human CD3 (Research Grade Teplizumab Biosimilar) Antibody, Catalog # MAB9929?
- The light chain is kappa.
