Citrate Buffered Saline is widely used in biological and medical research for its ability to maintain a stable pH environment. It is commonly employed in cell culture applications to provide optimal conditions for cell growth and maintenance. In immunology, it is utilized as a diluent for antibodies and other reagents, ensuring consistent performance during assays. Additionally, it plays a crucial role in blood collection and storage, where it acts as an anticoagulant by chelating calcium ions, preventing clot formation. This makes it essential for procedures like plasma separation and transfusion medicine. Its buffering capacity also makes it suitable for use in diagnostic kits and as a washing solution in various laboratory protocols.
