Il-20 (IL20) ELISA Kit for Human

Principle of the assay: human IL-20 ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for IL-20 has been precoated onto 96-well plates. Standards(E.coli,L25-E176) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for IL-20 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human IL-20 amount of sample captured in plate.
Background: Interleukin-20 (IL-20) is a protein belonging to the IL-10 family of cytokines. IL-20 is produced by activated keratinocytes and monocytes and transmits an intracellular signal through two distinct cell-surface receptor complexes on keratinocytes and other epithelial cells. By radiation hybrid analysis, the IL20 gene was mapped to chromosome 1q32, where it is tightly linked to the IL10, IL19, and MDA7 genes within a 195-kb region, the IL10 family cytokine cluster. IL-20 regulates proliferation and differentiation of keratinocytes during inflammation, particularly inflammation associated with the skin. In addition, IL-20 also causes cell expansion of multipotential hematopoietic progenitor cells.

Small volumes of IL20 elisa kit vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

MBS176554 is a ready-to-use microwell, strip plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the IL-20 (IL20) ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range in biological research samples containing IL20. The ELISA analytical biochemical technique of the MBS176554 kit is based on IL20 antibody-IL20 antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect IL20 antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, IL20. Appropriate sample types may include undiluted body fluids and/or tissue homogenates, secretions. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).
