WebJun 17, 2024 · Before you begin. Before starting the protocol, two compounds are needed: the lead chemical matter (compound 1) that was determined to have efficacy in a phenotypic screen for enhancing astrocytic apoE, and a photoaffinity labeling (PAL) probe (compound 2) designed from 1 that still retained phenotypic activity. The hypothesis is … Webnevertheless, photoaffinity labeling is the only general method to investigate such ligand–receptor interactions at a molecular level.1 Recently we introduced the protocol of using the bifunctional photoaffinity probe (BPP)31 coupled with tandem mass spectrometry (MS) to facilitate the often tedious photoaffinity
