BES, Free Acid is a zwitterionic buffer that is used in biochemistry and molecular biology research in the pH range of 6.15 - 8.35 for wide applicability to biochemical studies. A protocol has been reported for the use of BES buffered saline in the calcium phosphate mediated transfection of eukaryotic cells with plasmid DNA.
A zwitterionic buffer that is used in research in the pH range of 6.15 - 8.35;BES may be employed as binding buffer in modified Eagle′s medium during the binding assay of human melanoma cells. It may be used as biobuffer to investigate the aqueous medium self-assembly of heterometallic CuII/Li 3D coordination polymers.
