[Isoelectrofocusing in the study of the heterogeneity of immunoglobulins G in man with or without proliferative symptomatology].


In the present investigation, the immunoglobulins G of human sera were studied after isoelectrofocusing using polyacrylamide flat bed gel. The heterogeneity of immunoglobulins was demonstrated in normal serum as well as in pathological situations. Isoelectrofocusing study was performed using the total serum or the immunoglobulin's preparations obtained… (More)
