WebThe ELISPOT is a powerful functional assay used to detect biological activity and immunological secretions from immune cells. In this chapter, we specifically discuss T cell ELISPOT methods for the detection of secreted cytokines. A detailed protocol is given enabling the detection of interferon gam … WebJul 28, 2024 · In Vitro Stimulation Increases the Frequency of Cytokine-Secreting DENV-Specific Memory T Cells After Infection. The finding that low IFN-γ responses were detected by ex-vivo ELISPOT assays led us to evaluate responses using a more sensitive double color TNF-α and IFN-γ, cultured ELISPOT assay.
