This Human IL-12 p70 ELISPOT Ready-SET-Go! reagent set contains the necessary reagents for performing enzyme linked immunosorbent spot (ELISPOT) assays for high resolution frequency analysis of IL-12 p70-secreting cells. This assay specifically recognizes the p70 (heterodimer), without interference by p40 monomer or dimer. This ELISPOT reagent set is pre-titrated for optimal spot development.
