Product Summary for Mouse IL-2 ELISpot Kit

ELISpot kits are highly sensitive, microplate-based assays for the detection of cytokine secreting cells. This kit is designed for the detection and enumeration of mouse IL-2. Complete ELISpot kits are ready-to-run and require no assay development or refinement.

This ELISpot assay employs a capture antibody specific for mouse IL-2, pre-coated onto a PVDF-backed microplate. Appropriately stimulated cells are pipetted directly into the wells and the immobilized antibody in the immediate vicinity of the secreting cells binds secreted mouse IL-2. Following wash steps and incubation with a biotinylated detection antibody, alkaline-phosphatase conjugated to streptavidin is added. Unbound enzyme is subsequently removed by washing and a substrate solution (BCIP/NBT) is added. A blue-black colored precipitate forms at the sites of cytokine localization and appears as spots, with each individual spot representing an individual mouse IL-2 secreting cell. The spots can be counted with an automated ELISpot reader system or manually using a stereomicroscope.

Product Features for Mouse IL-2 ELISpot Kit

Background: IL-2

IL-2 (Interleukin 2) is a critical cytokine in T cell biology. It promotes T cell activation and expansion, the development, maintenance and function of regulatory T cells (Treg), and the differentiation of CD8+ T cells into terminal effector cells and memory cells. IL-2 signals through a receptor complex composed of CD25/IL-2 R alpha, IL-2 R beta, and the Common gamma Chain (gamma c). IL-2 R beta is also a component of the IL-15 receptor complex. Gamma c is also a signaling subunit in the receptors for IL-4, -7, -9, -15, and -21.
