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.

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.
