Hi David, Considering a good number of markers will get up- or downregulated on stimulation, it would be useful to let us know just what the purpose of the stimulation is in what seems to be a straightforward phenotyping experiment. Otherwise, you can use any number of lectins or antiCD3/CD28 beads in whole blood, but please beware of cells clustering together after stimulation. Why do you think you'd lose rare populations in Ficoll? Perhaps an erythro lysis step would be a simple alternative but again, everything hinges on what you're trying to accomplish here.

I would like to avoid ficoll because I do not want loose rare cell populations. I would also like to avoid anything that would prevent phenotyping with CD3, 4, 8, 45RA, 62L etc... Thanks, David A.
