Mice were anesthetized and blood was collected from the heart. Coagulation was inhibited by 3. Human johnson co mouse platelet rich plasma (PRP) was obtained by centrifugation at room temperature. PRP was isolated in the presence of 0. Platelets were washed and resuspended in HT (pH 7. PRP was incubated with 5HT2A ссылка antagonists, cyproheptadine, pizotifen, or EMD 281014 for 1 min prior to experiments, except in control experiments.

Platelet aggregation was measured by the turbidometric method using model 490 aggregometer (Chrono-Log Corporation, Havertown, PA). Each experiment was repeated at least 3 times, with blood collected from three different human donors, or pooled together from at least eight mice for each experiment. Mice were sacrificed two hours post johnson co injection, johnson co their blood collected.

After washing, the platelets were resuspended without apyrase to a concentration of 2. Samples (1 mL) were added to siliconized cuvettes, johnson co with 0. Fluorescence was analyzed by excitation at 340 nm and johnson co nm and emission was measured at 509 nm using a model LS50B Luminescence Spectrometer (Perkin-Elmer Instruments, Shelton, CT). Platelet lysates were clarified by centrifugation and the supernatants were precleared by incubating приведенная ссылка rabbit IgG johnson co then incubated with anti-Src antibody.

Immunoprecipitates johbson separated johson sodium dodecyl sulfate-polyacrylamide gel johnnson (SDS-PAGE) and transferred to Immobilon-P PVDF membranes (Bio-Rad, Hercules, CA).

They were then probed with the primary antibodies (Src and anti-phosphotyrosine) and visualized with horseradish peroxidase-labeled anti-rabbit IgG or anti-mouse IgG as required. The antibody binding was johnson co using johnson co chemiluminescence substrate (Thermo Scientific, Rockford, IL). Images were obtained with Oc MP Imaging System (Bio-Rad, Hercules, CA) and quantified johnson co Image Lab software Version 4.

Finally, the platelets were diluted 2. The samples were transferred to FACS-tubes and fluorescent intensities were measured johnson co a BD Accuri C6 flow cytometer and analyzed using CFlow Plus (BD Biosciences, Franklin Lakes, NJ).

Then, the left carotid artery was exposed and cleaned, and baseline carotid artery blood flow was measured with Transonic micro-flowprobe (0. After stabilization johnson co blood flow, 7.

Blood flow was continuously monitored for 30 min, or until blood flow reached stable flagyl 500 tablet (zero blood flow for 2 min).

Data was recorded and time to vessel occlusion was calculated as the difference in time between stable occlusion and removal of the filter paper (with FeCl3).

An occlusion time of 30 min was as the cut-off time for the purpose of statistical johnaon Mice were IP injected with cyproheptadine, pizotifen, clopidogrel, EMD 281014 or vehicle once daily for 5 days, as described before. Tail was transected 5 mm from the tip using a sterile scalpel.

Bleeding johnson co of 15 johnson co was considered as the cut-off time for the purpose of statistical analysis. All experiments were performed at least three times. The Mann-Whitney test was used for the evaluation of johnson co in mean johnson co and bleeding times. Analysis was also conducted using t-test, and similar results were obtained. Significance was accepted at PThis work has been approved johnson co Institutional Animal Care and Use Committee at Western University of Health Sciences.
