Invitrogen™ Mouse Th1/Th2 Uncoated ELISA Kit

Description

The Mouse Th1/Th2 Uncoated ELISA Kit contains pre-matched antibody pairs, plates and reagents for performing quantitative enzyme linked immunosorbent assays (ELISA) to detect and quantify protein levels of mouse Th1/Th2 proteins (Interferon gamma, IL-2, IL-4 and IL-10). Wash Buffer and Stop Solution are needed to complete the ELISA reaction and are sold separately. Principle of the method ELISAs are designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody is coated to the bottom of the wells of a microplate, which is an overnight process. Samples, standards, or controls are then added into these wells and bind to the immobilized (capture) antibody. A sandwich is formed by the addition of the second (detector) antibody, a substrate solution is added that reacts with the enzyme-antibody-target complex to produce measurable signal. The intensity of this signal is directly proportional to the concentration of target present in the original specimen.

T helper type 1 (Th1) cells and T helper type 2 (Th2) cells are both a lineage of CD4 effector T cells. Th1 and Th2 are involved in promoting cell-mediated immunity. Th1 cells secrete IFN-gamma, IL-2, IL-10, and TNF-alpha/beta, which are required for host defense against intracellular viral and bacterial pathogens. Th2 cells secrete IL-4, IL-5, IL-9, IL-13, and IL-17E/IL-15, which are required for humoral immunity and play an important role in coordinating the immune response to larger extracellular pathogens.
