Abstract
We present here a method for electrophoretic identification of hemoglobin variants in many individual erythrocytes simultaneously, which is made possible by instruments developed in our laboratory. The system spaces and aligns the erythrocytes along a common origin and prevents “doubling up” of cells. Unambiguous separation of different hemoglobins (Hbs) occurred from single erythrocytes, such as Hbs A, C, F. Staged micrographs showed that hemoglobins of differing mobility from a single cell arise from a single point source of hemoglobin. In principle this capability is applicable to other proteins and could facilitate investigation at a cellular level into a variety of questions pertaining to gene action.
