Descrição geral
Bradykinins bind and activate two GPCRs, termed B1 and B2 (gene names BDKRB1 and BDKRB2, respectively), which signal through Gq and Gi. B2 is widely expressed in a constitutive fashion, whereas B1 expression is induced during inflammation. B2 appears to mediate much of the activity of kinins in vasodilation, arthritis, edema, and nociception (Leeb-Lundberg et al., 2005). Chemicon′s B2 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 B2 interactions with bradykinin. The membrane preparations exhibit a Kd of 0.18 nM for [3H]-bradykinin. With 5.0 μg/well, B2 Membrane Prep and 0.4 nM [3H]-bradykinin, a greater than 4-fold signal-to-background ratio is obtained.

Especificações
Inucbation Conditions
RECOMMENDED 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] Bradykinin, [2,3-prolyl-3,4-3H(N)] (Perkin Elmer #NET-706)
Wash Buffer: 50 mM Hepes, pH 7.4, 500 mM 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 4-fold signal:background with 3H-labeled bradykinin at 0.4 nM
