Concentration of total equine erythrocyte cytoplasmic amino acids (orange) and corresponding external media (blue) for erythrocytes which had been pre-loaded with amino acids prior to washing and incubation in PBS at 37 °C (mean ± SE, n = 3). Significant differences were marked between the initial value and the subsequent time points *p < 0.01; **p < 0.001
