Binding
FLAP Binding Assay: The assay below is used to test the modulatory activity of compounds against FLAP. Human and mouse FLAP-encoding DNA was amplified by polymerase chain reaction and cloned into pFastBac1 (Invitrogen) with a NH2-terminal 6-His tag for expression in Spodoptera frugiperda (Sf-9) cells. FLAP-containing membranes were prepared as was a FITC-labeled FLAP modulator (3-(3-(tert-butylthio)-1-(4-chlorobenzyl)-5-(quinolin-2-ylmethoxy)-1H-indol-2-yl)-2,2-dimethylpropanoic acid). The FLAP binding assay is performed in HTRF format (homogeneous time resolved fluorescence). FLAP-containing membranes (1 μg/well final for human) are incubated in the presence of the HTRF ligand, [5-[({[2-(2-{3-[3-(tert-butylsulfanyl)-1-(4-chlorobenzyl)-5-(quinolin-2-ylmethoxy)-1H-indol-2-yl]-2,2-dimethylpropanoyl}hydrazino)-2-oxoethyl]sulfanyl}acetyl)amino]-2-(6-hydroxy-3-oxo-3H-xanthen-9-yl)benzoic acid] (25 nM final), a terbium labeled anti-His tag antibody (0.5 ng/well final, from Cisbio) and compounds. The reaction is allowed to proceed for two hours after which the plate is read on an Envision plate reader in HTRF mode.
