Species reactivityReacts with: Human
Human IL-8 ELISA kit is designed for the quantitative measurement of IL-8 supernatants, buffered solutions, serum and plasma samples. (Genecards: CXCL8)
A monoclonal antibody specific for IL-8 has been coated onto the wells of the microtiter strips provided. Samples, including standards of known IL-8 concentrations, control specimens or unknowns are pipetted into these wells. During the first incubation, the standards or samples and a biotinylated monoclonal antibody specific for IL-8 are simultaneously incubated. After washing, the enzyme Streptavidin-HRP, that binds the biotinylated antibody is added, incubated and washed. A TMB substrate solution is added which acts on the bound enzyme to induce a colored reaction product. The intensity of this colored product is directly proportional to the concentration of IL-8 present in the samples.
This kit will recognize both endogenous and recombinant Human IL-8.

FunctionIL-8 is a chemotactic factor that attracts neutrophils, basophils, and T-cells, but not monocytes. It is also involved in neutrophil activation. It is released from several cell types in response to an inflammatory stimulus. IL-8(6-77) has a 5-10-fold higher activity on neutrophil activation, IL-8(5-77) has increased activity on neutrophil activation and IL-8(7-77) has a higher affinity to receptors CXCR1 and CXCR2 as compared to IL-8(1-77), respectively.
Sequence similaritiesBelongs to the intercrine alpha (chemokine CxC) family.
modificationsSeveral N-terminal processed forms are produced by proteolytic cleavage after secretion from at least peripheral blood monocytes, leukcocytes and endothelial cells. In general, IL-8(1-77) is referred to as interleukin-8. IL-8(6-77) is the most promiment form.
- Information by UniProt
IL-8 detected in supernatants from control cells (C) or cells stimulated for 24 hours with 50 ng x mL-1 of PMA (ab120297) (P), and with the addition of 1 ug x mL-1 of LPS (Sigma) (P/L) for the last 6 hours. The positive control is included (Pos.). Results shown after background signal was subtracted (duplicates +/- SD).
