What are Biosimilar Antibodies?

Biosimilar antibodies are research-grade antibodies that are highly similar in structure, function and sequences to the approved original therapeutic antibodies. They are produced through recombination technology and have the same variable regions from the corresponding therapeutic antibodies, which making them reliable and more cost-effective research tools and alternative reagents in drug development and basic research.

CUSABIO has successfully expressed and validated many research-grade biosimilar antibodies, covering a variety of popular targets. All these research-grade biosimilar antibodies can be directly used as positive controls in drug discovery or used for rapid verification of the biological functions of target protein.

Why Choose CUSABIO Biosimilar Antibodies?
