ApplicationFluoroSpot
AnalyteIFN-γ, IL-13

Shipping and Storage

ShippingShipped at ambient temperature.
StorageStore antibodies, fluorophore conjugates, and FluoroSpot enhancer at 4-8 °C upon receipt. Plates may be kept at room temperature.
Shelf lifeAt least 12 months from date of receipt.
PBMC were incubated for 48h in the absence (250,000 cells/well) or presence (50,000 cells/well) of anti-CD3 antibody and the number of cells secreting IFN-γ and/or IL-13 was analyzed by FluoroSpot. Double-secreting cells were determined as spots having the same center point in an image overlay of IFN-γ and IL-13 images. Mabtech IRIS was used for analysis.

IFN-γ

Analyte description

Interferon-γ (IFN-γ) is the only type II interferon. This proinflammatory cytokine is secreted by activated T cells and NK cells. It activates macrophages and endothelial cells and regulates immune responses by affecting APCs, T cells, and B cells. Production of IFN-γ by helper T cells and cytotoxic T cells is a hallmark of the Th1-type phenotype. Thus, high-level production of IFN-γ is typically associated with effective host defense against intracellular pathogens.

IL-13

Analyte description

Interleukin 13 (IL-13) is produced by Th2-type cells, mast cells, and NK cells in response to activation. It regulates the secretion of IgE by B cells and the Th2-type cell development and suppresses inflammatory responses by regulation of macrophage function.
