Invitrogen™ IL-8 Human Matched Antibody Pair

Description

The Human IL-8/NAP-1 Matched Antibody Pair Kit comes with pre-matched antibody pairs,standards,and streptavidin-HRP to develop your own enzyme linked immunosorbent assays (ELISA) to detect and quantify protein levels of human IL-8. Buffer reagents and microplates needed to complete the ELISA reaction are sold separately. Principle of the method ELISAs are designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody is coated to the bottom of the wells of a microplate,which is an overnight process. Samples,standards,or controls are then added into these wells and bind to the immobilized (capture) antibody. A sandwich is formed by the addition of the second (detector) antibody,a substrate solution is added that reacts with the enzyme-antibody-target complex to produce measurable signal. The intensity of this signal is directly proportional to the concentration of target present in the original specimen.

IL-8 (Interleukin-8) is a 72 amino acid pro-inflammatory CXC chemokine designated CXCL8,secreted by endothelial cells and monocytes,which acts as a major chemoattractant for neutrophils and also T cells and basophils. 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. Cancer studies have demonstrated a role for IL-8 in the angiogenesis and growth of tumours. 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.
