Introduction to ADME and Caco-2 assays

During the process of Drug Discovery, a particular compound must go through different tests to determinate whether this new entity will be efficient and safe for patients. Within this variety of tests, one key subgroup pretends to describe the compound’s interactions with physiology and its properties. ADMET, which stands for “absorption distribution, metabolism, excretion and toxicity” is a preclinical stage in which candidate compounds properties are assessed and their performance in front of different aspects of biological interactions are described.

This ADME segment is part of Preclinical Development. Preclinical studies include in vitro and in vivo testing, and it aims to determinate a new drug’s properties and effectiveness, before it is provided to hospitals for research in human beings (clinical trials). Preclinical studies were traditionally performed in animals (in vivo), but the use of in vitro testing is actually increasing, as they are less expensive and more practical, replacing and complementing in vivo approaches.



Introducing CacoReadyTM

CacoReady™ is an innovative cell-based and ready-to-use kit.

The kit consists of 24 and 96 insert-integrated permeable support seeded with differentiated and polarized Caco-2 barriers on polycarbonate microporous filters.

CacoReady™ Allows in vitro intestinal absorption evaluation of drug targets. CacoReady™ is flexible since plates can be used up to 5 days after ideal cell barrier differentiation at day 21. CacoReady™ is a time and cost-saving tool for early stage drug discovery and development 


  • Provides 21-day cell barrier allowing reduction of in-house maintenance and handling of Caco-2 cell cultures.
  • High flexibility as the kit is useable up to 5 days after after 21-day cell barrier differentiation.
  • High reproductibility.
  • Time saving and cost-effective.
