The importance of immunological assay methods for validating the efficacy of pharmacokinetics and pharmacodynamics of drugs has recently increased due to the rapid growth and development of bio-therapeutics, including antibody and protein therapeutics.

In response, ABION CRO aims to offer research infrastructure optimized for the quantitative and qualitative analysis of ELISA-based protein therapeutics and high-quality analytical services for investigators involved in new drug development and biotechnology-related research through a variety of scientific tools and well-established SOPs.

We conduct method validation in compliance with ICH Q2 guidelines to guarantee reliable and accurate data.

ELISA (enzyme-linked immunosorbent assay) is a widely used assay designed for the accurate detection and quantitative measurement of antigen or antibody at very lowconcentrations. This assay is a highly convenient biochemical technique and serves as a sensitive analytical tool for the toxicological, immunological, pharmacokinetics, and pharmacodynamics analyses of biologics as part of new drug development.

ABION CRO offers a vast range of ELISA assays, including direct and indirect ELISA, sandwich ELISA, and multiplex. Multiplex, in particular, is a highly effective beadbased analysis tool that allows simultaneous detection of up to 100 analytes in a single sample and requires less samples, reagents, and time than conventional single-plex assays.

We also provide customized assay designs for many applications to suit your analyte combinations or the intended targets in order to accomplish your specific research goals. We guarantee superior services and ensure effective test results through our integrated and automated technology platforms, which are coupled with our extensive expertise.
