Mouse IFN-gamma ELISpot Kit

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 IFN-gamma. Complete ELISpot kits are ready-to-run and require no assay development or refinement.

This ELISpot assay employs a capture antibody specific for mouse IFN-gamma, 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 IFN-gamma. 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 IFN-gamma secreting cell. The spots can be counted with an automated ELISpot reader system or manually using a stereomicroscope.

PRODUCT FEATURES

• Detect and quantitate individual cells secreting mouse IFN-gamma
• High sensitivity - ELISpot assays can measure responses with frequencies well below 1 in 100,000 cells
• No in vitro expansion of cells required
• High-throughput - ELISpot assays use only a small number of primary cells
