The Electrophoretic Mobility of Erythrocytes of Patients with Malignant Tumors.

The microelectrophoresis apparatus consists of a laterally oriented rectangular chamber and Ag-AgCl electrodes. This has been described in detail previously.5 Since that description several minor technical changes have been made in order to facilitate cleaning and repair of the apparatus. The sintered glass discs which separate the observation chamber from the electrode compartments are vertically oriented and are fused to the ends of male halves of 10/30 Pyrex#{174} joints which join the electrode compartments. The female halves of these joints are sealed to the side arms of the observation chamber. The joints are sealed with Apiezon#{174} grease and held together with steel springs. The pore size of the sintered discs is 0.9-1.4 (instead of 4-5.5 ). The silver-silver-chloride electrodes are stored in situ in the electrode compartments which contain saturated KCI and a small amount of crystalline KC1. The KC1 is changed every 1-2 weeks as part of the general cleaning of the apparatus.
