Normally, the addition of acid to a solution will lower its pH and the addition of a base will raise its pH. If the solution is a buffer, however, its pH will be changed less than would be expected from the amounts of acid or base that are added.

WebA buffer with a low metal-binding constant is suitable for the study of metal-dependent enzymatic reactions. If your experimental design requires the use of a metal, then you should choose a buffer that does not form a complex with that specific metal. Buffers should be stable and resist enzymatic and nonenzymatic degradation. WebJan 7, 2024 · By Go Life Science Updated on January 7, 2024.
