For platelet counts, peripheral blood was collected from the retro-orbital sinus using EDTA coated tubes, and assessed using a Hemavet Analyzer (Drew Scientific, FL). For functional platelet assays, blood was collected into heparinized tubes (BD Biosciences, San Jose, CA). Platelet-rich plasma was prepared as previously described (REF). For flow cytometry, 50 uL of whole blood was added to 200 uL Tris-buffered saline (20mM Tris-HCl, 137mM NaCl). After further dilution with 1 mL of 2 mM CaCl2 in modified Tyrodes-HEPES buffer (5mM HEPES, 140mM NaCl, 2.7mM KCl, 5.5mM dextrose, 0.42mM Na2HPO4, 12mM NaHCO3), platelets were stained with anti-GPIIb/IIIa (CD41/61) FITC together with anti-GPIIb/IIIa (CD41/61) PE (JONA clone) or anti-P-selectin PE (Emfret, Würzburg, Germany). During staining, platelets were also stimulated with 1mM adenosine 5-diphosphate (ADP; Sigma-Aldrich, St. Louis, MO, USA), 0.1U or 0.01U Thrombin (Roche, Basel, Switzerland), or 3mM Thromboxane A2 analog U46619 (Cayman Chemical, Ann Arbor, MI, USA) at 37°C for 20min. Reactions were stopped by adding 300 ul 0.5% PFA (in PBS) to the samples and analyzed using a FACS Calibur cytometer (BD Biosciences, San Jose, CA, USA) and FlowJo software (TreeStar, Ashland, OR, USA).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
