title: The formulation of buffers and media for enzyme histochemistry.
abstract: Buffer solutions and incubating media for enzyme histochemistry are discussed in terms of pH, ionic strength and buffering capacity. A specially written program is presented. This program enables (i) buffers and media of known pH and ionic strength to be formulated; (ii) the ionic strength of a buffer solution of known molarity, and (iii) the thermodynamic acid dissociation constant of a buffer substance, to be calculated.
