A large fluorescence intensity increase is observed upon calcium association with Fluo-4. The dye is delivered to the cell interior using an acetoxymethylester form of Fluo-4, where the intracellular esterase activity results in the charged species being released and trapped within the cytoplasm of the cell. hence, influx of calcium to this cytoplasmic pocket, via release from intracellular pools and the phospholipase C cascade can be detected. By co-expressing the CXCR2 receptor and the promiscuous Galpha 16 protein, activation of this chemokine receptor is directed into this phospholipase C cascade resulting in intracellular calcium mobilization.The CHOK1 cells stably transfected with human CXCR2 and the promiscuous Galpha 16 protein were maintained in a log phase of growth at 37 C. and 5% CO2 in the following media: Iscove's.Calcium Fluorescence Assay: The assay is based on the detection of intracellular calcium changes detected by the selective, calcium-chelating dye, Fluo-4 (Molecular Probes).

A large fluorescence intensity increase is observed upon calcium association with Fluo-4. The dye is delivered to the cell interior using an acetoxymethylester form of Fluo-4, where the intracellular esterase activity results in the charged species being released and trapped within the cytoplasm of the cell. hence, influx of calcium to this cytoplasmic pocket, via release from intracellular pools and the phospholipase C cascade can be detected. By co-expressing the CXCR2 receptor and the promiscuous Galpha 16 protein, activation of this chemokine receptor is directed into this phospholipase C cascade resulting in intracellular calcium mobilization.The CHOK1 cells stably transfected with human CXCR2 and the promiscuous Galpha 16 protein were maintained in a log phase of growth at 37 C. and 5% CO2 in the following media: Iscove's.Calcium Fluorescence Assay: The assay is based on the detection of intracellular calcium changes detected by the selective, calcium-chelating dye, Fluo-4 (Molecular Probes).
