Ionomycin increases flow of extracellular Ca2+ Into cells leading to increased T-cell activation by IFNg: Excellent publishable, performed ideally.
By Li Zhu on 01/23/2019
Assay Type: In Vitro
Species: Human
Cell Line/Tissue: Primary Cd8+ T-cells

Ionomycin was used as a calcium ionophore to bring large amounts of extracellular Ca2+ into activated CD8+ T-cells. With high intracellular Ca2+, this led to increased activation of CD8+ T-cells as measured by IFNg production via intracellular flow cytometry.
