Abstract

DISC electrophoresis has been shown to be a rapid means of producing very high resolution separations of proteins1,2. Various histochemical methods, such as the periodic acid–Schiff and the Feulgen techniques, have been applied to the gel columns to identify various proteins after electrophoretic separation. Although the reproducibility of disc electrophoresis is quite good, it is difficult to correlate results of staining each of several replicate separations by different methods because one cannot be completely certain that each protein fraction migrated exactly the same distance in each replicate gel column, and various histochemical techniques may not show protein bands seen by others, thus making it difficult to determine relative positions of the bands.
