BV510 Mouse Anti-Human IL-8 

Description

The G265-8 monoclonal antibody specifically binds to both the 72 and 77 amino acid isoforms of human Interleukin-8 (IL-8). IL-8 is secreted as an 8-9 kDa, non-glycosylated proinflammatory chemokine protein also known as chemokine (C-X-C motif) ligand 8 (CXCL8). IL-8 is synthesized as a 99 amino acid precursor that is proteolytically processed into several isoforms. The 72 amino acid isoform is produced by monocytes, macrophages, granulocytes, epithelial cells, and fibroblasts in response to pro-inflammatory stimuli including cytokines and microbial agents. It is also expressed by endothelial cells, fibroblasts, keratinocytes, lymphocytes, and a variety of tumor cells. In response to IL-4, IL-10 and TGFβ, the cellular production of IL-8 is inhibited. IL-8 is crucial for the activation and recruitment of neutrophils to inflammatory sites. IL-8 is also a chemoattractant for basophils and T-lymphocytes. IL-8 possesses angiogenic activity and can be associated with tumor angiogenesis and metastasis. The 77 amino acid IL-8 isoform is primarily produced by endothelial cells. This larger isoform is reportedly a less potent neutrophil activator than the 72 amino acid isoform. IL-8 binds to and signals through two G-protein-coupled receptors, IL-8RA (CXCR1/CD181) and IL-8RB (CXCR2/CD182).

The antibody was conjugated to BD Horizon™ BV510 which is part of the BD Horizon™ Brilliant Violet™ family of dyes. With an Ex Max of 405-nm and Em Max at 510-nm, BD Horizon™ BV510 can be excited by the violet laser and detected in the BD Horizon™ V500 (525/50-nm) filter set. BD Horizon™ BV510 conjugates are useful for the detection of dim markers off the violet laser.

Preparation and Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with BD Horizon™ BV510 under optimum conditions, and unconjugated antibody and free BD Horizon™ BV510 were removed.

Product Notices

1. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
2. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
3. An isotype control should be used at the same concentration as the antibody of interest.
