This Human IL-12 p70 ELISA Ready-SET-Go! reagent set (with or without high-affinity binding microwell plates) contains the necessary reagents, buffers and diluents for performing quantitative enzyme linked immunosorbent assays (ELISA). This Human IL-12 p70 ELISA Ready-SET-Go! reagent set specifically measures the bioactive, heterodimeric form of IL-12, p70, without interference by p40 monomer, homodimer, or IL-23 (p19/p40). This ELISA reagent set is specifically engineered for accurate and precise measurement of human IL-12 p70 protein levels from samples including serum, plasma, and supernatants from cell cultures.
