Electrophoresis by the microscope method: A simple experimental assembly

1. 1. A new assembly for microelectrophoresis is described. It consists of an electrode unit properly separated from the test suspension for the avoidance of contamination, and a Northrop-Kunitz cell arranged laterally, that is, with its long and short axes horizontal and its intermediate axis vertical. 2. 2. The performance of the new assembly has been compared with those of the conventional Abramson-Moyer horizontal and vertical cells by mobility studies on erythrocytes of man, guinea pig, and rabbit, and has been found equally reliable. 3. 3. It was concluded that the new arrangement is capable of performing satisfactorily all of the functions for which both the conventional horizontal and the conventional vertical arrangements have been used previously.
