| | THP-1 Cells Pyroptosis Assay |
| Description: | 1. Seed THP-1 cells (25,000 cells/well) containing 1.0 μg/ml LPS in 40 μl of RPMI medium (without FBS) in 96-well, black walled, clear bottom cell culture plates coated with poly-D-lysine (VWR #734-0317)2. Add 5p compound (8 points half-log dilution, with 100M top dose) or vehicle (DMSO 0.1% FAC) to the appropriate wells3. Incubate for 3 hrs at 37° C., 5% CO24. Add 5 μl nigericin (Sigma #N7143) (FAC 5 μM) to all wells5. Incubate for 1 hr at 37° C., 5% CO26. At the end of the incubation period, spin plates at 300×g for 3 mins and remove supernatant7. Then add 50 μl of resazurin (Sigma #R7017) (FAC 100 μM resazurin in RPMI medium without FBS) and incubate plates for a further 1-2 hrs at 37° C. and 5% CO28. Plates were read in an Envision reader at Ex 560 nm and Em 590 nm9. IC50 data is fitted to a non-linear regression equation (log inhibitor vs response-variable slope 4-parameters). |
