IL-31 ELISA kits

We make ELISA kits for IL-31 in human. This page explains how they differ, so you can pick the one your experiment needs.

What differs between these kits

Which detection system

Available with Streptavidin-ALP or Streptavidin-HRP. You add the streptavidin conjugate as a second incubation after the biotinylated antibody, which amplifies the signal. Alkaline phosphatase (ALP) and horseradish peroxidase (HRP) perform equivalently, so that choice usually comes down to the substrate and reader you already work with.

About IL-31

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.
