%X Switching from ELISpot to FluoroSpot enables the analysis of spot-forming units representing cells producing different cytokines as well as the frequencies of spots derived from cells co-secreting multiple cytokines. Due to the fluorescent read-out signal, sophisticated reader instruments can also measure the relative spot volume, making it possible to differentiate between spots generated by cells secreting different levels of one or more cytokines. Here we describe how triple FluoroSpot assays can be used to define polyfunctional T cells secreting multiple cytokines and how different T-cell populations can differ in the levels of cytokines they secrete.
