Effects of Storage Time on Total Protein and Globulin Concentrations in Bovine Fresh Frozen Plasma Obtained for Transfusion

Table 1

Mean, median, and confidence interval 95% (95% CI) of total protein (TP) concentrations (biuret method), concentrations of albumin (ALB) and alpha-1, alpha-2, beta-1, beta-2, and gamma globulin fractions (agarose gel electrophoresis), and calculated albumin/globulin (A/G) ratios in fresh plasma samples and plasma samples stored frozen (−20°C) and then thawed, collected from 20 adult cows for transfusion purposes.
