CURDLAN GEL, EVALUATED AS A POLYSACCHARIDE SUPPORT BY ELECTROPHORESISOF SUBSTITUTED BENZENES

Curdlan gel was evaluated as a support for electrophoresis of low mole cular weight aromatic compounds in comparison with polyacrylamide gel. This gel was found to have the excellent ability to recognize the pos itional (o-, m- and p-) isomers of phthalic acid and phenylenediamine, which were not resolved by polyacrylamide gel electrophoresis. Furthe rmore, the polysaccharide support gave superior resolution for hydroph ilic compounds such as hydroxylated benzoates. Hydrophobic alkylated b enzoates were much better resolved in polyacrylamide gel rather than i n curdlan gel.
