Need a robust assay?

Decisions are based on screening data. Primary, on target, in vitro screen data THAT YOU CAN TRUST is the most important element you need for your program. Working with a trusted partner is paramount for project success.


Data you can trust

Reliable data is essential for decision-making, and the most important element you need for your program. We have identified multiple flaws in more than 30% of the assays being run by other groups. With our team, you’ll have primary, on target in vitro screening data that you can trust. Partnering with NuChem gives you the skill and reliability needed for project success.
