| ChEMBL | PDSP Secondary Binding target: SIGMAR1 - Compounds are tested at 10 uM concentration, plate are incubated at room temperature in the dark for 90 minutes. Reaction are stopped by vacuum filtration onto 0.3% polyethyleneimine soaked filter mats using Filtermate harvester. Scintillation cocktail is then melted onto microwave-dried filters on a hot plate and the radio activity is counted in Microbia counter. Compounds showing a minimum of 50% inhibition at 10 uM concentration are carried forward in this secondary binding assay to determine equilibrium binding affinity. | B | 5.05 | pKi | 8846.06 | nM | Ki | EUbOPEN Chemogenomics Library - PDSP Secondary Binding |
