CD69 timing

I haven't looked at mitogen activation, but in co-stimulation assays of
human peripheral blood T-cells with anti-CD3 and a number of other
antibodies and integrins I've found fairly high levels of CD69
expression between 18-24 hrs.

	my recollection was this antigen was upregulated at ~ 4-6 hours
post activation. i dont remember when it down-regulated though,
w/respect to its maintained presence at 24 hours

		Hi everyone, I want to study the effect of a certain
drug on CD69 expression after mitogen activation of human blood
lymphocytes. What is the best timing to analuze this marker?. Is 24 hrs
after activation too late?
		Many thanks
