Review assay metadata, readout intent, target linkage, and publication context from the same page.

Binding
Radioligand binding assay: human or rat P2X7-1321N1 cells were collected and frozen @ −80° C. On the day of the experiment, cell membrane preparations were made according to standard published methods. The total assay volume was 100 μl:10 μl compound (10×)+(b) 40 μl tracer (2.5×)+50 μl membrane (2×). The tracer used for the assay was tritiated A-804598. The compound can be prepared as described in the literature. (Donnelly-Roberts, D. Neuropharmacology 2009, 56 (1), 223-229.) Compounds, tracer and membranes were incubated for 1 hour @ 4° C. The assay was terminated by filtration (GF/B filters pre-soaked with 0.3% PEI) and washed with washing buffer (Tris-HCl 50 mM). The IC50 generated in the binding assay was corrected for tracer concentration and affinity of the tracer to derive at the affinity (Ki) of the test compounds
