Immunogen: HeLa cells transfected with human BLT1 • Clone designation: 7B1 • Host: Mouse • Cross-Reactivity: (+) BLT1; (−) BLT2, CysLT1, and CysLT2 receptors • Species Reactivity: (+) Human • Isotype: IgG2a • Application(s): FC, IF, and IHC of frozen sections • The human BLT1 receptor is a GPCR that mediates the proinflammatory effects of leukotriene B4 (LTB4). Northern blotting reveals that the BLT1 receptor is highly expressed in leukocytes, U937 cells, and to a much lower extent in spleen and thymus.
