Shipping and Storage


Shipped at ambient temperature.


Store 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 (250,000 cells/well) were incubated for 48 hours in the absence or presence of PPD and the number of cells secreting IFN-γ and/or IL-5 was analyzed by FluoroSpot. Double-secreting cells were determined as spots having the same position (centre point) in an image overlay of LED490, FITC (IFN-γ) and LED550, Cy3 (IL-5) images. Spot analysis was made with Mabtech IRIS.

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.

Analyte description

Interleukin 5 (IL-5) is a pleiotropic cytokine primarily produced by T and NK cells.  IL-5 specifically controls the survival, differentiation, and chemotaxis of eosinophils. But initially, IL-5 was characterized by its ability to support the growth and terminal differentiation of B cells.
