BES buffered saline can be used to study molecular biology, DNA and RNA purification, biological buffers and zwitterionic compounds. BES buffered saline has been used in a study that identified how to increase the transfection efficacy and subsequent long-term culture of resting human pancreatic duct epithelial cells.
