RE: Appropriate number of events to collect for 3 color flow cytometry ?

I think for a Gaussian distribution, the 99% confidence interval for the
mean is (stand deviation)/(2.6*sqrt(N)), N - number of events. From this
you can estimate N. I think people usually prefer to collect more events
than would be necessary from this estimate, and with blood it's easy
enough to do so. (But I am not really a flow professional)

Subject: Appropriate number of events to collect for 3 color flow
cytometry ?

Hello Again!
 
I am sorry for posting too many emails in the forum, can't get any
better advice than here.
 
I am just wondering and interested to know that if there is any
particular number of events (say 10,000 or 20,000) I need to collect
while doing 3 color flow cytometry in whole blood. 
 
Thanks for your help.
 
Best wishes,
 
Abdul
