Add DCFDA 30 minutes before and incubate at 37 with CO2 and wash the cells with PBS (to reduce aggregation: or use filtering) and immediately analyze by FACS at FITC/FL-1 channel
Did you get the answer of your question? I am stuck in this step and i don't know how to do it with THP-1. When i treat the labelled THP-1 cells with H202 (Hyedrogen peroxide) . and then see the results, no ros is produced. Can you please help me. I will be very thankful to you.
