frozen sections of human renal carcinomas were studied in indirect immunofluorescence using antibodies against intermediate filaments of cytokeratin , desmin and vimentin type , and against proximal tubular brush border and distal tubular tamm-horsfall glycoprotein antigens , as well as with fluorochrome-labeled lectins in an attempt to study the origin and stage of differentiation of renal carcinomas .
