Flow cytometry is increasingly used for cytokine detection where it serves to complement
ELISA (enzyme-linked immunosorbent assay) and ELISPOT assays. Since it is possible to
stain both extracellular epitopes and intracellular cytokines on the same cells, this is a
powerful technique for analysing cytokine expression in defined cell populations. However
unstimulated cells do not express cytokines. Thus, appropriate stimulation is a prerequisite
for studying cytokine expression. Here phorbol 12-myristate 13-acetate (PMA)/ionomycin in …
