Glucose Veronal Buffer is primarily used in biological and biochemical research for maintaining a stable pH environment during experiments. It is particularly useful in enzyme assays and immunological studies where precise pH control is critical for accurate results. The buffer is also employed in cell culture applications to support cell growth and maintain physiological conditions. Additionally, it is utilized in diagnostic laboratories for preparing reagents and stabilizing samples. Its ability to provide a consistent pH makes it valuable in electrophoresis and other analytical techniques requiring controlled environments.
