New York, USA – February 25, 2021 – Profacgen, a state-of-the-art protein service provider located in NY, USA, providing custom protein services in the biological sciences, now offers various services for PROTAC In Vitro Evaluation.

In vitro (cell-based and non-cell-based assays) assessment of candidate PROTAC is often based on biological activity against target proteins, which helps to identify binding affinity, permeability, degradation and stability, cytotoxicity, and others. In in vitro tests, different kinds of cells and tissues (possibly from humans, animals, microorganisms and even plants) can provide evidence about changes in the activity and function of target proteins caused by PROTAC.

Now, Profacgen provides various in vitro evaluation services for its customers’ projects with professional scientist team.
