Biosimilar Antibodies for Biomedical Research

What are CST biosimilar antibodies?

CST biosimilar antibodies are research-grade recombinant monoclonal antibodies that are structurally and functionally similar to existing FDA-approved products. These biosimilar antibodies have been developed using sequences that are highly similar to existing therapeutic products and are effective substitutes that can be used for research purposes. These cost-effective biosimilar alternatives are ideal for preclinical research to study the biological effects of complex molecules, perform benchmarking studies, or be used in assay development without paying the hefty price of a pharmaceutical-grade product.

Biosimilar antibodies from CST are 100% manufactured in-house and rigorously validated to meet our stringent standards, so you can trust they will perform as expected–the first time, and every time. We can ensure a consistent supply of these high-quality antibodies by maintaining full control over our product development and supply line.

CST biosimilar antibodies are for research use only and feature:

  • High-quality recombinant monoclonal antibodies
  • Structure and sequences that are highly similar to FDA-approved products
  • Low endotoxin concentrations: < 0.1 EU/μg of antibody
  • Ideal formulations: supplied in 1x PBS solution, BSA- and azide-free
