Using an automated cell electrophoresis system equipped with an image processor, we studied electrophoretic mobilities of erythrocytes of healthy donors and of patients suffering from systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), hypergammaglobulinemia and diabetes mellitus (DM). On average, erythrocytes from SLE patients showed mean electrophoretic mobilities (EPM) which were significantly lower (p < 0.005) than the EPM of red blood cells of normal donors. Evaluation of mean EPM and standard deviations revealed that three groups of SLE patients could be distinguished regarding the electrophoretic behavior of their erythrocytes. Some patients had red blood cells with normal EPM, others had erythrocytes with significantly reduced EPM, and a third group appeared to have both kinds of erythrocytes. In addition, erythrocytes of various SLE patients showed enhanced resistance to lysis by glycerol and their membranes contained less quantities of band 3 proteins.

Electrophoresis: Overview

Electrophoresis is a powerful analytical separation technique that relies on the differential migration of charged species when subjected to an electric field. The core strength of electrophoresis lies in its ability to separate high-molecular-weight species in complex mixtures. It has found widespread use in biochemistry, molecular biology, and analytical chemistry, allowing the separation of compounds like amino acids, nucleotides, carbohydrates, and proteins with excellent resolution.

Disorders of Erythrocytes

Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
