| Description: | A prepared WP was homogenated and a membrane fraction was collected with high-speed centrifugation. A compound of the present invention was added to the plate and [3H]-PGD2 was also added. A platelet membrane, a protein concentration is 2 mg/mL, was added and mixed in the plate, and placed on ice for 2 hours. The reaction solution was transferred to a low protein-adsorptive filter and washed with a wash solution eight times using a cell harvester. After the final washing, water was removed sufficiently, and scintillator was added. DP inhibitory activity was investigated by measuring [3H] by using Micro Beta. |
