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.
