Biosimilars have become indispensable tools in modern laboratory research. While widely recognized for their therapeutic impact, biosimilar monoclonal antibodies (mAbs) also play a critical role behind the scenes — helping researchers explore new biological pathways, evaluate assay performance, and accelerate the transition from early-stage studies to clinical applications.

At ProSci, we support this work by providing researchers with a comprehensive selection of research-grade biosimilars designed for consistency, reliability, and confidence in the lab.

Why Biosimilars Matter in Research

Apart from their medicinal uses, biosimilar monoclonal antibodies have demonstrated tremendous value in clinical and research environments alike. These biologics — often referred to simply as biosimilars — are frequently used as benchmark reagents in laboratory studies.

Because biosimilars are developed using well-established reference products, researchers benefit from existing data around toxicity, efficacy, and biological activity. This makes them ideal tools for:

· Assay development and characterization studies

· Comparability, immunogenicity and pharmacokinetic testing

· Mechanism-of-action research

· Identifying off-target or novel applications

By working with reagents that are already well characterized, scientists can move more efficiently from discovery-phase research toward clinical drug development.

A Comprehensive Biosimilars Portfolio

ProSci offers an extensive catalog of over 800 research-grade biosimilar antibodies, supporting scientists across a broad range of research areas — including oncology, immunology, neuroscience, inflammation, hematology, and infectious disease.

Each biosimilar in our collection is produced with the same attention to quality and performance that researchers expect from ProSci reagents, helping ensure reproducibility across experiments and confidence in downstream data analysis.

Expert Support Beyond the Catalog

In addition to our expansive biosimilars offering, ProSci’s dedicated team of custom antibody specialists provides unmatched expertise in antibody design, development, purification, and scale-up. Whether you’re optimizing an existing workflow or developing a new research tool, our team is here to support advanced research needs from concept through production.

This combination of breadth, quality, and expertise support allows researchers to focus on what matters most — generating meaningful data and driving scientific progress.
