We have compared 23 compounds, with and without transphosphorylating properties, as buffer systems for human serum alkaline phosphatase activity, with p -nitrophenylphosphate as substrate. Relative enzyme activity in four representative buffers at near-optimal conditions was ethylaminoethanol > diethanolamine > 2-amino-2-methyl-1-propanol > carbonate. Transphosphorylation was demonstrated in the two buffers in which the enzyme was most active, ethylaminoethanol and diethanolamine. The optima… Expand
