Obtaining original therapeutic-grade antibodies for drug discovery is often expensive and impractical. To address this challenge, Antibodies.com is offering a comprehensive range of biosimilar antibodies.

What Are Biosimilar Antibodies?

Biosimilars are recombinant monoclonal antibodies that share an identical amino acid sequence with an approved therapeutic antibody. Produced in mammalian cell lines, they are engineered to mimic the specificity, structure, function, and efficacy of the reference product. While natural biological variations (like glycosylation) prevent them from being perfect replicas, these biosimilars are optimised for Research Use Only (RUO). They offer a cost-effective solution for assay development and disease mechanism studies without the high cost of pharmaceutical-grade equivalents.

Uncompromised Quality and Purity

Quality is critical for sensitive research. Our biosimilar antibodies are >95% pure, low endotoxin, and preservative-free. Antibodies.com ensures consistency through rigorous quality control.

• Purity Assessment: Confirmed via SDS-PAGE and SEC-HPLC to visualise aggregates and ensure monodispersity
• Bioactivity Testing: Binding affinity established using flow cytometry and ELISA
• Functional Assays: Validated via internalisation, ADCC, and in vivo inhibition assays

Additionally, formulations utilise histidine and sucrose to maximise protein stability and minimise aggregation.

Applications in Research

Biosimilars serve as excellent benchmarking tools and cost-effective alternatives for:

• Mechanistic Studies: Investigating biological effects of therapeutics
• Benchmarking: Comparing new drug candidates during pre-clinical identification
• Diagnostic Assays: Optimising drug concentrations and dynamic ranges
• Biophysical Analysis: Characterising binding via Surface Plasmon Resonance (SPR)
