A specific method for the determination of free acetate in blood and tissues

Abstract
A specific enzymic method for the quantitative determination of acetate in the range 1-15[mu]g. in a volume not exceeding 3 ml. is described. The procedure involves diffusion in Conway microdiffusion units and reaction with sulphanilamide by means of a pigeon-liver enzyme preparation, which is stable at -20[degree] for at least 1 year. The method is highly specific for acetate. Interference from a number of substances examined is negligible. The accuracy is about 0.3 [mu]g. (S.D.) independent of the concentration in the range covered.
