| Description: | Prothrombinase Assay:The effect of test compounds on prothrombinase activity is measured via thrombin generation. Briefly, 12.5 μL human factor Xa is incubated in 10 mM HEPES buffer, pH 7.4, 2 mM CaCl2, the final concentration is 0.5 nM, and add 12.5 μL human platelets (1×107 mL−1) for 10 minutes at 37° C. The reaction is initiated by adding 25 μL prothrombin, the final concentration is 0.5 μM and 2 μL the assay buffer containing 2% (V/V) DMSO (uninhibited control) or various concentrations of the compounds to be tested diluted in the assay buffer containing 2% (V/V) DMSO. After 20 minutes, thrombin activity is measured by adding 48 μL substrate of S-2238 (Chromogenix) at the final concentration is 50 μM. |
