An optimized method for the assay of the red blood cell--age-related enzyme aspartate aminotransferase.
Three methods of preparation of red blood cell concentrate for erythrocyte aspartate aminotransferase measurement were compared: (1) filtration of whole blood through a cellulose column (n = 36); (2) washing of whole blood and aspiration of buffy coat after centrifugation (n = 48); (3) optimized method with washing without aspiration of buffy coat (n = 229).
