Hemoglobin human serum fractionated

El-FFF is a technique devoted to the fractionation of proteins which is reflected in the number of papers applying this technique to protein separations. The possibilities of El-FFF were first demonstrated by Caldwell for the separation of albumin, lysozyme, hemoglobin, and y-globulin in two different buffer solutions (pH 4.5 and 8.0) [35]. Later, the performance of an El-FFF channel with flexible membranes [36], a channel with rigid membranes [256], or a circular channel [260] for the separation of proteins were described. In these studies, human and bovine serum albumin, y-globulin (bovine), cytochrome C (horse heart), lysozyme (egg white) and soluble ribonucleic acid (t-RNA), as well as denaturated proteins, were successfully separated.
