Application:
BES (CAS: 10191-18-1) is a zwitterionic buffer that is used in biochemistry and molecular biology research. It is one of the "Good" buffers developed in the 1960's for wide applicability to biochemical studies. BES buffer is suitable for use in systems where a calcium phosphate-DNA complex formation is desirable. BES is used as a buffer to maintain the pH of the solutions in biological experiments. BES is useful for diagnostic assay manufacturing industry. BES induces cross-linking between sulfonated polyimide chains in sulfonated polyimide membranes. BES acts as biobuffer to investigate the aqueous medium self-assembly of heterometallic CuII/Li 3D coordination polymers.
