Quantification of Platelet counts in circulated bovine blood. (A) Bar graph presentation of platelet counts at different time points of bovine blood circulation using Trillium^® Biosurface circuit. Data presents the average of five technical replicates using the same blood samples at 5 min, 30 min, and 55 min with no significant changes between time points. (B) Bar graph presentation of platelet counts at different time points of bovine blood circulation using Xcoating^TM circuit. Data presents the average of five technical replicates using the same blood samples at 5 min, 30 min, and 55 min with no significant changes between time points. (Mean ± SD, P < 0.05, five technical replicates).
