IL-8 Protein (SIL8) in ELISA Std
Sandwich ELISA analysis of human IL-8 was performed using a Human IL-8 Colorimetric ELISA kit (Product # EH2IL8) by loading 50 ul per well of Human IL-8 Recombinant Protein (Product # SIL8) in dodecuplicate at 1000, 400, 160, 64, 25.6, and 0 pg/ml across a 3 ug/ml mouse anti-Human IL-8 (Product # M801) pre-coated plate and incubating for 1 hour at room temperature. The plate was washed, and then incubated with 50 ul per well of a biotinylated mouse anti-human IL-8 monoclonal antibody (Product # M802B) in duplicate at 0.25 ug/ml for 1 hour ... View More

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.
