Assay description: Determination of SMARCA2 and SMARCA4 degradation in MV-4-11 cells by Western blot
MV-4-11 cells were plated in 6 well plates using complete Iscove's Modified Dulbecco's Medium. On the third day, compounds of present invention were added to cells from 10 mM stocks made in DMSO. Each concentration of compound was tested with DMSO not exceeding final percentage of 0.1 in the cells. Cells were incubated with the compound for 16 hours followed by harvesting with IX RIPA lysis buffer containing protease inhibitor cocktail. Equal amount of protein was loaded on SDS PAGE gel for electrophoresis. Western blot was carried out for detection of either SMARCA2 or SMARCA4 antibody. Beta-Tubulin antibody was used as loading control. Percentage of SMARCA2 or SMARCA4 degradation was calculated using formula % Degradation = 100-(normalized band intensity in treated sample/normalized band intensity in DMSO sample) * 100. Here, "ND" refers to Not determined.
