Comments

Reference 1 provides informations based on mathematicals models for the right choice of the best buffer substance for investigations on pH-dependent processes. Unfortunately it requires detailed knowledge in mathematics.CHES interferes with the Lowry assay. It is suitable for the crystallization of phosphotriesterase (50 mM) or in the chemical modification of bacteriorhodopsin (10 mM).
