General description

BES (N,N-bis(2-hydroxyethyl)-2-aminoethanesulfonic acid) is a useful secondary standard biochemical buffer. Useful pH range for BES is 6.4 to 7.8. It is useful for diagnostic assay manufacturing industry. BES, a sulfonic acid-containing cross-linking agent, induces cross-linking between sulfonated polyimide chains in sulfonated polyimide membranes.

Application

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.
