Count on Monolith NT.Automated to run your single-dose and affinity screen campaigns. Because it uses MST to measure interactions, the single-dose screen identifies not only hits, but also gives you information about compound‐induced aggregation — super important to keep false positives from entering later stages of the drug discovery process. Additionally, you don’t have to modify the automated workflow of the subsequent affinity screen, because all the steps can be done using the same automation setup used in the single-dose screen.
A single-point screen of small molecule inhibitors with labeled p38 alpha kinase identified five hits A through F (upper panel, dotted lines represent hit thresholds). Next, an affinity screen measured the binding affinities for the 5 hits (lower panel). Four of them had Kds in the nanomolar range, and one was determined to be a non-binder (F).
