Mouse IL-5 ELISpot Kit Summary
* Provided that the recommended microplates, buffers, diluents, substrates and solutions are used, and the assay is run as summarized in the Assay Procedure provided.
PRODUCT SUMMARY
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-5. 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-5, 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-5. 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-5 secreting cell. The spots can be counted with an automated ELISpot reader system or manually using a stereomicroscope.

Preparation and Storage
Background: IL-5
IL-5 (Interleukin-5) is a secreted cytokine that is expressed as a covalent dimer. It is produced by activated Th2 cells, eosinophils, mast cells, and iNKT cells and promotes eosinophilic and basophilic differentiation and activation. IL-5 signals through a receptor complex containing IL-5 R alpha and the Common beta Chain/CD131 on eosinophils and basophils. Naturally occurring soluble forms of IL-5 R alpha retain the ability to bind IL-5 and limit its bioavailability.
