      DescriptionChemiScreen™ BLT1 Membrane Preparation
      OverviewHuman BLT1
      Background InformationBLT1 receptor is a Gi-coupled GPCR that binds primarily to the eicosanoid leukotriene B4. Macrophages, leukocytes and eosinophils express BLT1, and in vivo, BLT1 appears to mediate leukocyte migration and inflammation (reviewed in Brink et al., 2003). Chemicon's BLT1 membrane preparations are crude membrane preparations made from our proprietary stable recombinant cell lines to ensure high-level of GPCR surface expression; thus, they are ideal HTS tools for screening of antagonists of BLT1 interactions with Leukotriene B4. The membrane preparations exhibit a Kd of 1.3 nM for [3H]-Leukotriene B4. With 5.0 μg/well BLT1 Membrane Prep and 1 nM [3H]-Leukotriene B4, a signal-to-background ratio of approximately 3-fold is obtained.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: Q15722 # Receptor for extracellular ATP > UTP and ADP. The activity of this receptor is mediated by G proteins which activate a phosphatidylinositol-calcium second messenger system. May be the cardiac P2Y receptor involved in the regulation of cardiac muscle contraction through modulation of L-type calcium currents. Is a receptor for leukotriene B4, a potent chemoattractant involved in inflammation and immune response.
      SIZE: 352 amino acids; 37557 Da
      SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
      TISSUE SPECIFICITY: Expressed at highest levels in heart, skeletal muscle and at lower levels in brain and liver. High level of expression in lymphoid tissues.
      PTM: Phosphorylated by GRK6 upon leukotriene B4 binding; which promotes desensitization.
      SIMILARITY: SwissProt: Q15722 ## Belongs to the G-protein coupled receptor 1 family.
      Incubation ConditionsRECOMMENDED ASSAY CONDITIONS: Membranes are mixed with radioactive ligand and unlabeled competitor (see Figures 1 and 2 for concentrations tested) in binding buffer in a nonbinding 96-well plate, and incubated for 1-2 h. Prior to filtration, a GF/C 96-well filter plate is coated with 0.33% polyethyleneimine for 30 min, then washed with 50mM HEPES, pH 7.4, 0.5% BSA. Binding reaction is transferred to the filter plate, and washed 3 times (1 mL per well per wash) with Wash Buffer. The plate is dried and counted.

      Binding buffer: 50 mM Hepes, pH 7.4, 5 mM MgCl2, 1 mM CaCl2, 0.2% BSA, filtered and stored at 4°C

      Radioligand: [3H] Luekotriene (Perkin Elmer# NEX378)

      Wash Buffer: 50 mM Hepes, pH 7.4, 500mM NaCl , 0.1% BSA, filtered and stored at 4°C.

      One package contains enough membranes for at least 200 assays (units), where a unit is the amount of membrane that will yield greater than 2.5-fold signal:background or 500 cpm with 3H-labeled Leukotriene B4 at 1 nM
