CAPS SODIUM SALT CAS:105140-23-6

Buffering Agent: CAPS sodium salt acts as a buffering agent, helping to maintain a stable pH in solutions. It has a pKa value of approximately 10.4, which allows it to maintain a constant pH within a range of 9.7 to 11.1.

Protein Electrophoresis: CAPS sodium salt is commonly used as a buffering agent in protein electrophoresis techniques, such as SDS-PAGE (sodium dodecyl sulfate-polyacrylamide gel electrophoresis) and western blotting. It helps to maintain a stable pH and provides excellent separation of proteins.

Enzymatic Reactions: CAPS sodium salt is often used as a buffer in enzymatic reactions, as it can maintain pH stability over a wide range. It helps to optimize enzyme activity and stability, which is critical for many biochemical assays and experiments.

Cell Culture Media: CAPS sodium salt is also added to cell culture media as a buffering agent. It helps to stabilize the pH of the culture medium, which is necessary for the growth and survival of cells in vitro.
