1. 1. This paper confirms the increase in sensitivity obtained for erythrocyte UIS measurement by pre-incubation of the red cells in a 0.2% Triton-X 100 solution containing 1 mmol/1 ZnSO4 and dithiothreitol as described by Piepkorn et al. (1978). 2. 2. To achieve optimal precision in this assay a su...
