hi Simona,

We look at rare cells in the blood and do the staining after RBC-lysis. We tested both ways and staining after lysis works the best for our application.
I would suggest you to test both ways and then decide.

> I think traditionally clinical labs stain in whole blood and then lyse the red cells. There are many published papers and protocols on this method. The NCCLS also has recommended procedures which you can refer to. I can't see why you would use any more antibody staining in whole blood vs. rbc lysed.
