| Sumario: | Paper electrophoresis of sugars and other substances with cetyltrimethylammonium borate at pH 9.6 gives rise to a pattern of mobilities different from that found with potassium borate, thus making certain separations possible that are not obtained with the potassium salt. There seems to be a general trend towards a reversal in the order of mobilities with the cetyltrimethylammonium buffer. The observed mobilities have been interpreted as the net results of two contrary effects: a strong and uniform endosmotic flow towards the anode and an opposite and variable movement towards the cathode. The latter displacement would take place by association of the solutes with the positively charged ionic micelles that are present in the solutions of cetyltrimethylammonium salts. Applications of this behavior might lead to the separation of other substances. © 1962. |
