description Product Description
ADA is widely used as a buffering agent in biochemical and molecular biology research. It helps maintain a stable pH in various experimental setups, particularly in enzyme assays and protein studies. Its effectiveness in the pH range of 6.0 to 7.2 makes it suitable for applications involving biological systems. Additionally, ADA is utilized in diagnostic kits and medical research to ensure accurate and consistent results. Its buffering capacity is also beneficial in cell culture media, where maintaining a stable environment is crucial for cell growth and viability.
