Cells were treated with dexamethasone (10 μM) or without dexamethasone for 72 hours and then assessed for C1q binding following exposure to rituximab and human serum for 1 hour. The mean fluorescence intensity of FITC-C1q was not significantly different following dexamethasone treatment. This table demonstrates the mean of 3 samples from one experiment. P is insignificant for all 9 B-NHL cells.
