Description: The monoclonal antibody N11 reacts specifically with the 77 amino acid form of IL-8 (IL-877, IL-8(1-77), CXCL877) and does not react with the more common 72 amino acid form. Frequently referred to as "endothelial" IL-8, the 77 amino acid form is secreted in cultured leukocytes. The 72 amino acid form is the result of efficient cleavage of an N-terminal pentamer from IL-877 after secretion. IL-8 is a C-X-C chemokine with potency in neutrophil chemotaxis and activation. IL-877 has decreased chemotactic activity when compared to IL-872, but has other specific pro-apoptotic and tumor cell chemotactic activities. IL-877 has recently been shown to be the major isoform present in premature neonates due to deficiency in serum protease activity that is not seen in term neonates. Applications Reported: This N11 antibody has been reported for use in immunoblotting (WB). Applications Tested: This N11 antibody has been tested by immunoblot of peripheral blood mononuclear cells stimulated with LPS for 4 hours. This can be used at 1-5 µg per mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Purity: Greater than 90%, as determined by SDS-PAGE. Aggregation: Less than 10%, as determined by HPLC. Filtration: 0.2 µm post-manufacturing filtered.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.
