[Transparency of analytical results found by different methods of electrophoresis studies on casein (author's...

The electrophoretic mobility of the major casein components has been studied on different carriers. Besides free electrophoresis and paper electrophoresis starch gel, polyacrylamide gel and cellulose acetate gel have compared. With urea buffer mixtures of neutral to alkaline pH a mobility scale on all gels was found corresponding the order alphas-, beta-, kappa-, gamma-casein in the sense of decreasing mobility. The application of commercially available cellulose acetate strips for the investigation of genetic material in large numbers has been found to be sufficient. The transparency of polyacrylamide gel, starch gel and cellulose acetate gel results is guaranteed.
