4、ggregation but still counteractes the pronounced inhibition caused by PGD2 (30 nM) and BW245c (3 nM).Laropiprant blocks DP receptor-dependent increase in VASP phosphorylation, as well as inhibition of P-selectin expression, GPIIb/IIIa activation and in vitro thrombus formation. Laropiprant antagoniz

5、es theincreased platelet aggregation by TP and EP3 receptor activation. Laropiprant (10 M) and niacin inhibit invitro thrombus formation 2.PROTOCOLCell Assay 2 Vena8Fluoro+ Biochips are coated with collagen (200 g/mL) at 4C overnight and thereafter blocked withbovine serum albumin (10 g/mL) for 30 m

6、inutes at room temperature followed by washing steps. Wholeblood collected in sodium citrate is incubated with 3, 3-dihexyloxacarbocyanine iodide (1 M) in the dark for10 minutes. PGD2 (30 nM), BW245c (3 nM) are added 10 min before the start of perfusion, and the DPantagonist BWA868c or Laropiprant (

7、1 M) are added 10 min before the agonists. In another set ofexperiments whole blood is treated with niacin (3 mM), acetylsalicylic acid (1 mM) or Laropiprant (1 M and10 M) for 30 min. CaCl2 at a final concentration of 1 mM is added 2 minutes before the perfusion over thecollagen-coated chip. Perfusi

Computerized image analysis is performed by DucoCell analysis software, where the area coveredby the thrombus is calculated. Data are expressed as percent of area covered in a control sample 2.MCE has not independently
