I am using flow cytometer and trying to find out the cell concentration. For this purpose I am using CountBright™ Absolute Counting Beads. In its protocol it is saying "at least 1,000 bead events should be acquired to assure a statistically significant determination of sample volume". But when I am running my sample after adding 50 microlitre of the counting beads to sample, I am getting maximum 175 bead events. I tried even changing the different channels. Is it ok if I use this much less bead events for calculation of total count?
Thank you in advance for suggestions and help.
