(a) Two dimensional electrophoresis of a β-hexyl extract of human podocytes; (b) immuno-Western blot of a serum from one child with nephrotic syndrome; actin was identified on the basis of well-defined electrophoretic characteristics, spot 1 was characterized by MALDI-Mass; (c) immuno-Western blot of each patient with nephrotic syndrome and presence of anti-podocyte antibodies. Also in these cases, spots 1 and 2 were characterized by MALDI-Mass (see Table 2).
