About This Kit
The Human Interleukin-8 (Hu IL-8) ELISA kit offers a precise method for quantifying Hu IL-8 in diverse biological samples, including human serum, plasma, amniotic fluid, or cell culture medium. This highly specific assay is designed to exclusively recognize and measure both native and recombinant forms of Hu IL-8.
Principle of the method
The Human IL-8 solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) employs a meticulously selected pair of antibodies to capture the target analyte and quantitate its amount. Within the microplate wells, a target-specific antibody is pre-coated, facilitating the binding of the analyte during the assay. Upon the introduction of samples or standards they selectively bind to the immobilized (capture) antibody within the wells. The formation of a sandwich complex is achieved by adding a second (detector) antibody. Subsequently, a substrate solution is added, initiating a reaction with the enzyme-antibody-target complex, resulting in the generation of a measurable signal. The intensity of this signal is directly proportional to the concentration of the target present in the original specimen.
Target information
Interleukin 8 (IL-8, CXCL8) is a 72 amino acid pro-inflammatory factor which belongs to the CXC subfamily of chemokines, and are bound by the cell surface receptors IL-8RA and IL-8RB. IL-8 functions as a chemoattractant and potent angiogenic factor. The expression and secretion of IL-8 can be induced by diverse inflammatory stimuli in many cells, including macrophages and endothelial cells. In endothelial cells, IL-8 is present in storage vesicles called Weibel-Palade bodies. IL-8, first isolated from osteosarcoma cells, contains the ELR-motif (N-terminal Glu-Leu-Arg amino acid sequence) and signals through the CXCR1 and CXCR2 receptors. Previous nomenclature for IL-8 includes neutrophil activating protein 1 (NAP-1), granulocyte chemotactic protein 1 (GCP-1), monocyte-derived neutrophil-activating peptide (MONAP) and protein 3-10C. IL-8 and ten other members of the CXC chemokine gene family form a chemokine gene cluster in a region mapped to chromosome 4q. Cancer studies have demonstrated a role for IL-8 in the angiogenesis and growth of tumours, and IL-8 is believed to play a role in the pathogenesis of bronchiolitis, a common respiratory tract disease caused by viral infection.
