Product specifications

Intended use

This ELISA Flex kit is intended for the quantification of human IL-31 in solution. For research use only. Not for use in diagnostic procedures.

Serum/Plasma samples

Analysis of serum/plasma with this kit requires the use of ELISA diluent. The ELISA diluent blocks heterophilic antibodies from cross-linking the assay antibodies, thereby preventing false-positive read-outs. Heterophilic antibodies are commonly found in human serum/plasma. The ELISA diluent has been validated using from healthy human blood donors. It should be used for dilution of standard, samples, and detection antibody.

IL-31

Analyte description

Interleukin 31 (IL-31) is a cytokine belonging to the IL-6 family. It is mainly secreted by activated T cells, especially in Th2 helper cells, mast cells, macrophages, and dendritic cells. IL-31 mainly acts in the skin, lung, intestine, and nervous system, facilitating cell-mediated immunity against pathogens. The receptor for IL-31 is found on e.g. keratinocytes and endothelial cells and can be upregulated on activated monocytes. However, IL-31 is considered a Th2-type cytokine with different functions than other Th2-type cytokines. In transgenic mice overexpressing IL-31, the cytokine induces pruritus and dermatitis resembling human atopic dermatitis (AD). In humans, IL-31 has been associated with AD, atopic and contact allergies, airway hypersensitivity, and inflammatory bowel disease.
