Histological examination of the aldolase monomer composition of cells from human kidney and hypernephroid carcinoma.
Aldolase was specifically fixed in tissue sections by the use of antibody prepared either against aldolase A or against aldolase B. The localization of the antigen was demonstrated with the immuno-histochemical method. Aldolase A was found to be the predominant constituent in the cytoplasm of the distal tubules, the large vessels and the glomerula of normal kidney, and aldolase B in the proximal tubules. The collecting tubules and the capillaries contained a mixture of the two types. In the hypernephroid carcinoma cells only aldolase A could be found, but the capillaries within the tumor tissue did contain some aldolase B. Confirmation of these results was obtained by analysis of homogenate prepared with carefully selected tissue parts.
