| Description: | The clot-lysis test system configures the kinetics of clot formation and degradation in vitro and allows quantifying modulation of the process by selected test compounds.The test compounds were dissolved in 1% acetic acid and further complemented with an equal volume of DMSO. The resulting stock solutions were serially diluted in 0.5% acetic acid/50% DMSO. 1 μL aliquots of these solutions were placed into 384 well microplates (Greiner, black, transparent bottom), followed by 30 μL of diluted human citrated plasma (platelet-poor, final concentration: 5%; supplemented with fibrinogen, final concentration: 3 μM; dilution buffer: 20 mM HEPES, 150 mM NaCl, 0.01% Brij (pH 7)). The reactions were started by addition of 20 μL of CaCl2 (final concentration: 10 mM), and tPA (tissue plasminogen activator, final concentration: 0.2 nM) in dilution buffer, followed by an additional volume of 20 μL dilution buffer for improved mixing. The reactions were incubated at 37° C. Clot formation and degradation was monitored spectrophotometrically by kinetic optical density measurements at 405 nm. IC50 values were determined by comparing the resulting time courses with the time course of a blank control reaction. |
