Curdlan Gel, Evaluated as a Polysaccharide Support by Electrophoresis of Substituted Benzenes

Curdlan gel was evaluated as a support for electrophoresis of low molecular weight aromatic compounds in comparison with polyacrylamide gel. This gel was found to have the excellent ability to recognize the positional (o-m- and p-) isomers of phthalic acid and phenylenediamine, which were not resolved by polyacrylamide gel electrophoresis. Furthermore, the polysaccharide support gave superior resolution for hydrophilic compounds such as hydroxylated benzoates. Hydrophobic alkylated benzoates were much better resolved in polyacrylamide gel rather than in curdlan gel.
