Porcine IL-10 ELISpot Kit

This ELISpot assay employs a capture antibody specific for porcine IL-10, 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 porcine IL-10. 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 porcine IL-10 secreting cell. The spots can be counted with an automated ELISpot reader system or manually using a stereomicroscope.

Product Features for Porcine IL-10 ELISpot Kit

• Detect and quantitate individual cells secreting porcine IL-10
• 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
