Product description

Mouse IL-20 ELISA (Enzyme-Linked Immunosorbent Assay) Kit is an in vitro enzyme-linked immunosorbent assay kit used for quantitative determination of IL-20 in serum, plasma, and cell culture supernatants. Specific anti-IL-20 antibodies are pre-coated onto high-affinity enzyme plates. Standards and samples are added to the wells of the enzyme plate, and after incubation, IL-20 present in the sample binds to the solid-phase antibody. After washing to remove unbound substances, a detection antibody is added for binding and incubated, followed by washing, and then the enzyme complex (Streptavidin-HRP) is added for binding and incubated. After washing, a colorimetric substrateTMB is added for color development, avoiding light. The intensity of the color reaction is proportional to the concentration of IL-20 in the sample. The reaction is terminated by adding a stop solution, and the absorbance is measured at 450 nm wavelength (with a reference wavelength of 570 - 630 nm).

IL-20 belongs to the TGF-β superfamily. IL-20 binds two heterodimeric receptor complexes, IL-20 R alpha/IL-20 R beta and IL-22 R/IL-20 R beta. IL-20 is reported to enhances tissue remodeling and wound-healing activities and restores the homeostasis of epithelial layers during infection and inflammatory responses to maintain tissue integrity.

Storage

The assay kit can be stored at 2~8℃. Alternatively, the reagents can be stored according to the storage conditions provided in the component information to avoid contamination and repeated freeze-thaw cycles. Diluted working solutions should be used immediately and not reused. The shelf life is 1 year.
