Human IL-8 ELISA Kit is an in vitro enzyme-linked immunosorbent assay kit used for the quantitative determination of Human IL-8 (Interleukin-8) in serum and cell culture supernatants. Specific antibodies against Human IL-8 are pre-coated on high-affinity enzyme plates. Standard samples and test samples are added to the wells of the enzyme plate and, after incubation, the IL-8 present in the samples binds to the solid-phase antibody. After washing to remove unbound substances, a detection antibody is added and incubated to bind. Following another wash, an enzyme conjugate (Streptavidin-HRP) is added and incubated to bind. After washing, aTMB chromogenic substrate is added for color development in the absence of light. The intensity of the color reaction is proportional to the concentration of IL-8 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-8, also known as CXCL8, is produced by macrophages and epithelial cells. It is a member of the α or CXC chemokine family and has a molecular weight of 8-9 kDa. IL-8 is a chemotactic factor that can attract neutrophils, eosinophils, and T cells, but not monocytes. It also plays a role in neutrophil activation and is released from several cell types in response to inflammatory stimuli.

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.
