Biologics - PK, ADA, purity assays

Benchmark Antibodies provides a comprehensive portfolio of Research Use Only (RUO) Pharmacokinetic (PK), Anti-Drug Antibody (ADA), Anti-PEG, and Host Cell Protein (HCP) assay kits, reagents, and critical assay components designed to support biologics research, assay development, immunogenicity investigations, and bioprocess development. Our products enable researchers to accurately quantify therapeutic biologics, detect anti-drug antibodies (ADA), measure anti-polyethylene glycol (anti-PEG) antibodies in multiple species, and detect host cell protein (HCP) contaminants present in biologic products manufactured using recombinant expression systems.

Our PK, ADA, anti-PEG, and HCP assay solutions are developed to provide the sensitivity, specificity, and reproducibility required for reliable ligand-binding assays used in pharmacokinetic studies, immunogenicity research, process development, product characterization, impurity testing, biomarker investigations, and assay optimization. Whether developing new analytical methods, comparing biologic candidates, evaluating assay performance, monitoring immunogenicity, assessing PEG-specific immune responses, or quantifying residual host cell proteins during biologic production, Benchmark Antibodies supplies the reagents and expertise needed to support your laboratory.

Key features of Benchmark Antibodies PK, ADA, Anti-PEG, and HCP research solutions:
