I have been trying to develop a reproducible and specific method for
simultaneous surface and cytoplasmic staining. I have had problems with
most of the published methodology especially when attempting to use
an isotype control.
>>>I would also like to hear about successful methods for this-please
post to the discussion group as well! In fact, I would be grateful if
anyone can share a recipe for successful detection of intracellular
IL-4 and IFN-gamma: we have not been able to detect these (or IL-2)
using a variety of protocols on human cells in bulk culture, or in
human clones. Activation has been tried with PHA, PPD, PMA and solid
phase OKT3. Any offers?
