The monoclonal antibody 203/14F11 specifically recognizes human leukotriene B4 receptor 1 (BLTR-1). BLTR-1 is a seven-transmembrane, G-protein-coupled receptor. The receptor plays an important role in pro-inflammatory responses. Leukotrienne B4 receptors are distributed in various hematopoietic cells including monocytes, granulocytes, and lymphocytes. Leukotriene B4 (LTB4), a product of arachidonic acid metabolism, is the ligand for BLTR-1. The immunogen used to generate 203/14F11 hybridoma was a human BLTR-1-transfected cell line.
The antibody was conjugated to BD Horizon™ BUV805 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 805 nm. BD Horizon Brilliant BUV805 can be excited by the ultraviolet laser (355 nm) and detected with a 820/60 filter and a 770LP.
