CAPS SODIUM SALT CAS:105140-23-6

CAPS sodium salt is a zwitterionic buffer commonly used in biochemical and molecular biology applications. It has a pKa value of approximately 10.4, making it effective for pH ranges between 9.7 and 11.1. CAPS sodium salt is used in protein electrophoresis, enzymatic reactions, biological and chemical assays, and cell culture media. It provides resistance to pH changes caused by contaminants and has good solubility in water.

Application and Effect

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.
