Introduction:
Interleukin 8 (IL-8 or chemokine (C-X-C motif) ligand 8, CXCL8) is a chemokine produced by macrophages and other cell types such as epithelial cells, airway smooth muscle cellsand endothelial cells. Endothelial cells store IL-8 in their storage vesicles, the Weibel–Palade bodies.In humans, the interleukin-8 protein is encoded by the CXCL8 gene.IL-8 is initially produced as a precursor peptide of 99 amino acids which then undergoes cleavage to create several active IL-8 isoforms. In culture, a 72 amino acid peptide is the major form secreted by macrophages.
Principle of the Assay:
Incubate the acceptor beads coated with anti- IL-8 antibody 1,biotin conjugated anti-IL-8 antibody 2,and the sample to form a sandwich immune complex ( antibody 1-sample- antibody 2). the immune complex is the n incubated withdonor beads coated with streptavid into form a chemiluminescent complex, ensuring that the distance between the two beads is less than 200 nm. When the distance between the two beads is less than 200 nm, the donor beads is excited by light (680 nm), producing singlet oxygen which diffuses to the acceptor beads, inducing energy transfer. the acceptor beads absorb this energy and emit scattering light at 615 nm. the light signal is collected by a photosensitive detector, and the concentration ofIL-8in the sample is calculated through mathe matical fitting. In the absence of humanIL-8in the sample, no immune complex is formed, or the distance between the two beads exceeds 200 nm, exceeding the transfer distance for singlet oxygen, and the acceptor beads do not emit any light.
Application:
For quantitative detection of human IL-8 in buffer solution, serum, cell culture supernatant.
Storage and Expiration:
Store at 2-8℃ for 6 months.
