The 6C6 monoclonal antibody specifically binds to CD182. CD182 is also known as the interleukin-8 receptor B (IL-8RB), a G-protein-linked seven transmembrane domain protein, expressed on monocytes and granulocytes. It is also expressed on a subset of T cells. Both IL-8RA (CXCR1) and IL-8RB (CXCR2) are high affinity receptors for IL-8. IL-8 is an inflammatory cytokine which induces chemotaxis of neutrophils, basophils and T lymphocytes.
The antibody was conjugated to BD Horizon™ BUV496 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome of BD Horizon BUV395 with an Ex Max of 348-nm and an acceptor dye with an Em Max at 496-nm. BD Horizon BUV496 can be excited by the ultraviolet laser (355 nm) and detected with a 515/30 nm filter with a 450LP. Due to the excitation of the acceptor dye by other laser lines, there may be significant spillover into the channel detecting BD Horizon V500 or BV510 (eg, 525/40-nm filter). However, the spillover can be corrected through compensation as with any other dye combination.
