Human IL-31 PharmaGenie ELISA Kit (SBRS0775)

Interleukin-31 (IL-31) is a Th2-associated cytokine strongly implicated in pruritus, atopic dermatitis, and chronic inflammatory skin conditions. This Assay Genie kit enables quantitative measurement of human IL-31 in cell culture supernatants, plasma, and serum using a microplate-based immunoassay format. The standard curve covers a detection range of 31.25 to 2000 pg/mL, with a sensitivity below 10 pg/mL, supporting quantification of this low-abundance cytokine in dermatology and immunology research. The assay enables investigation of IL-31 signaling through the IL-31RA/OSMR heterodimeric receptor complex and is relevant to studies of atopic dermatitis biomarkers, cutaneous T-cell lymphoma, and allergic skin inflammation. Each microplate is supplied ready for in vitro research use only, with all reagents included for human-specific quantification of IL-31 protein levels across experimental conditions.
