Small Molecule Bioanalysis Services to Support Drug Development

Our Analytical Services department offers non-regulated small molecule bioanalysis services to determine accurate measurement of parent drug and/or metabolite concentration in various biological matrices to support ADME (absorption, distribution, metabolism, and excretion), DMPK (drug metabolism and pharmacokinetics), and DDI (drug-drug interaction) studies in drug development.

Our Approach to Bioanalysis

Bioanalysis is a sub-discipline of analytical chemistry providing a quantitative measurement of a drug and/or its metabolite(s) in various biological matrices. The SEKISUI XenoTech Analytical Services department has over 100 years of combined experience with pharma and CROs spanning multiple disciplines including in vivo bioanalytical support. Our team of experts can provide quality, non-GLP results in 2-4 business days.
