Free-flow electrophoresis of proteins in phenol-containing solvents at various pH values.
1. Several proteins were found to migrate when subjected to free-flow electrophoresis in buffered phenol-ethanediol-water (3:2:3, w/v/v) solvent mixtures. Mobility of these proteins changed with changing pH (apparent) values of this medium. A pH value of zero mobility for each individual protein could be estimated. 2. Founded on these observations, a high-voltage electrophoresis method in free-flowing buffer films was worked out. The method as presented here was particularly suitable for the separation of proteins on a preparative scale. Application of this and other protein fractionation techniques in dissociating media for the investigation of structural and other insoluble proteins was discussed.
