IL-31, produced mainly by activated CD4+ T cells, is a newly discovered helical cytokine belonging to the gp130/IL6 cytokine family. IL-31 is closely related in structure to IL-6, IL-11, and IL-27. Binding of IL-31 to its receptor activates JAK/STAT, PI3K/AKT, and MAPK pathways. IL-31 acts on a broad range of immune and non-immune cells and thus possesses potential pleiotropic physiological functions, such as regulating hematopoiesis and immune responses. Human IL-31 is also involved in inflammatory bowel disease, airway hypersensitivity, and dermatitis.

ELISA Detection - Quality tested

Recommended Usage

Each lot of this antibody is quality control tested by ELISA. For ELISA detection applications, a concentration of 0.8 µg/mL is recommended. To obtain a linear standard curve, serial dilutions of PCSK9 recombinant protein ranging from 2000 to 31.3 pg/mL are recommended for each ELISA plate.

It is recommended that the reagent be titrated for optimal performance.

Application Notes

The purified Poly5300 antibody is useful as the capture antibody in a sandwich ELISA assay, when used in conjunction with the biotinylated Poly5300 antibody as the detecting antibody.
