Multiple electrode aggregometry and ADP-receptors. Adding ASA (acetylsalicylic acid) reagent to a blood sample reduces the aggregation responses in ASPItest and COLtest. ASA irreversibly inhibits COX1 in platelets, thereby inhibiting the production of TXA2. The ASA Reagent is used as a quality control in the platelet function testing with Multiplate, allowing the assessment of abnormal platelet responses in ASPItest and COLtest. This reagent is used as a quality control in Multiplate platelet function testing. The GPIIb/IIIa antagonist blocks the binding of fibrinogen to the GPIIb/IIIa receptors, preventing the formation of platelet-fibrinogen bonds and resulting in significantly reduced platelet aggregation in response to all
Asa Gray Gray had to borrow money from his father. Soon he was able to repay his father and help his family by supplementing his income giving lectures outside of Harvard, including at the Lowell Institute. Gray was considered a weak lecturer, but because of his expert knowledge, he was highly regarded by his peers. His skills were better suited to teaching advanced rather than introductory classes. He also gained renown for his textbooks and high quality illustrations. Gray moved into what became known as the Asa Gray House in the Botanic Garden in the summer of 1844. It had been built
