Nature:
SA buffer is a colorless crystalline solid that dissolves in water. It has a certain acidity and can maintain the acid-base balance of the solution within a specific range.
Use:
SA buffer is widely used in biochemical experiments and clinical tests. It is mainly used in the determination of enzyme activity, protein precipitation and limited dilution of samples. In addition, SA buffer can also be used for the determination of various drugs, vitamins, metabolites and ascorbic acid (vitamin C) in blood and urine.
Preparation Method:
The SA buffer can be prepared by adding a certain amount of aromatic sulfonic acid powder to a certain amount of water, and fully stirring to dissolve it. During the preparation process, the pH of the solution can be adjusted as needed, usually in the range of pH 2-5.
Safety Information:
When using SA buffer, you need to pay attention to the following safety information:
