Glucose Veronal Buffer with EDTA is primarily used in biological and biochemical research. It is commonly employed in immunology and serology for complement fixation tests, which help detect the presence of specific antibodies or antigens in a sample. The buffer maintains a stable pH, while glucose provides an energy source for cells, and EDTA acts as a chelating agent to inhibit metal-dependent enzymatic reactions, ensuring accurate test results. It is also utilized in cell culture applications to maintain cell viability and prevent contamination by metal ions. Additionally, this buffer is used in electrophoresis and other laboratory techniques where precise pH control and metal ion sequestration are critical.
