Maintenance of Active Enzymes
Chapter
Abstract
A key requirement in enzyme work is to know the pH at all times; to control the pH a buffer is essential. It is also important to know the characteristics of the buffer being used and to have on hand a range of different buffers so that one most suited to the application is available. Over the decades of enzyme studies a great number of buffers have been used, and new ones are still being developed. There are several characteristics we need to know about a buffer
- (1)
pK a value
- (2)
Variation of pK a with temperature, ionic strength
- (3)
Anionic, cationic, or multiple charges on buffer species
- (4)
Interaction with other components, e.g., metal ions
- (5)
Solubility
- (6)
Expense
- (7)
UV absorption
