Measure therapeutic antibody drug concentrations with our 60+ PK assay kits. Built on a sandwich ELISA platform using anti-idiotype capture antibodies for drug-specific detection. Quantify drug levels in serum, plasma, and tissue homogenates for dose-exposure analysis, trough level monitoring, and PK/PD modeling. All products are designated Research Use Only (RUO) — not intended for diagnostic or therapeutic procedures. RUO

Why Researchers Choose abinScience

Anti-Idiotype Capture Drug-specific anti-idiotype antibodies as capture reagent — selectively measuring the therapeutic antibody without interference from endogenous immunoglobulins.
Quantitative & Reproducible Pre-validated standard curves with defined LLOQ and ULOQ. Intra- and inter-assay precision data provided. Supports ng/mL-level drug quantification.
Multi-Species Validated Tested in human, cynomolgus monkey, mouse, and rat matrices — supporting PK studies from first-in-animal through clinical development.
