Abstract
The electrophoretic patterns of the sera and urine of two cases of lipoid nephrosis have been obtained and have been compared with a typical pattern of normal serum. The patterns of the pathological sera deviated widely from the normal, indicating relatively low albumin and high globulin content. The comparison of the patterns of nephrotic sera cleared by centrifugation and by ether extraction shows that a large portion of the beta globulin consisted of a labile lipo-protein. The pattern of the nephrotic urine proteins resembled that of normal serum, with, however, significant differences.
