Presenter: Dr. Katsuhiro Kanda, Senior Engineer in Bio Systems Design at Hitachi High-Tech Corporation


D-PREX is an assay methodology to evaluate total hepatocellular drug dispositions from drug uptake to both biliary and basolateral efflux simultaneously. D-PREX is predominantly utilized to assess supernatant fractions collected by a systematic assay procedure following consistent analysis and time-course sampling. In addition, D-PREX only exposes drugs to intact cell cultures, which leads to intracellular metabolism, resulting in simultaneous assessment of not only parent compounds but also their metabolite distributions. In this webinar, a technological overview will be presented along with assay examples of D-PREX, which is currently available as a contract research service by SEKISUI Medical supported by SEKISUI XenoTech. “D-PREX” is a registered trademark of Hitachi High-Tech Corporation in the US and Japan.

Key concepts discussed in this webinar will include:

  • Technological overview and principle of D-PREX assay
  • Sequential sampling of supernatants prior to final cell lysate sampling for reproducible, high-throughput analyses
  • Simultaneous evaluation of biliary and basolateral efflux from identical cell culture samples
  • Simultaneous profiling of parent compounds and metabolite distributions
  • Understanding the overall picture of drug and metabolite hepatocellular disposition profiles from the complex interplay of hepatic transport and metabolism
