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.
Mouse spleen cells (125,000 cells/well) were incubated overnight in the absence or presence of Concanavalin A (ConA) and the number of cells secreting IFN-γ and/or IL-2 was analyzed by FluoroSpot. Single cytokine secreting cells as well as double-secreting cells were determined. Spot center was used to identify spots from double-secreting cells, visualized in an image overlay of LED490, FITC (IFN-γ) and LED550 and Cy3 (IL-2). 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 2 (IL-2) is predominantly produced by activated T cells. IL-2 promotes the proliferation, differentiation, and survival of antigen-activated T cells and NK cells. After antigen stimulation, the cytokine also promotes the differentiation of T cells into effector and memory T cells. Therefore IL-2 plays an important role in the body's response to infection. IL-2 is also key to tolerance, as it promotes the differentiation of certain immature T cells into regulatory T cells in the thymus, ultimately preventing autoimmune diseases.
