Research Grade Biosimilar Antibodies

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?

Common Application Scenarios

Mechanism Research and Functional Validation

Serve as highly similar research tools for in vitro assessment of biological activities such as cytotoxicity and blocking effects of antibody drugs, enabling in-depth investigation into their mechanisms of action.

Drug Development and Quality Control Analysis

Used as critical reference standards or surrogate materials in the development of pharmacokinetic (PK) and immunogenicity (ADA) assays, facilitating method validation and bioequivalence evaluation.

Assay and Diagnostic Development

Function as reliable positive controls in Flow Cytometry, IHC, and other detection platforms, or are utilized in the development of companion diagnostics to ensure assay specificity and accuracy.

Preclinical In Vivo Efficacy Evaluation

With formulations suitable for in vivo administration, they can be directly applied in animal models for efficacy assessment and dose exploration, providing a foundation for preclinical research.
