Target analysis & bespoke screening strategies

Designing, running and interpreting the optimal assay cascade for your target


To identify and progress the most promising chemistry, and resolve the issues that inevitably arise, the right use of the right techniques at the right time is essential. This requires access to multiple techniques together with the expertise to run and interpret the results. This is a speciality at BioAscent and has developed by bringing together the use of biophysical, biochemical and cellular assays for over 150 molecular targets, providing corroborative and supportive data to create confidence in the results.


As part of our assay development/validation process we have developed a set of compounds known to cause interference in assays, so called PAINS activity, that can cause false positive results during screening (e.g. aggregators, redox cyclers, chelators etc.). We use these compounds during assay development to identify potential liabilities and can then either optimise the assay to minimise these ‘false positive’ effects, or in cases where these effects cannot be eliminated, we can put in place appropriate de-selection assays to quickly triage such compounds.
