title: Separation and purification of LDH and alkaline phosphatase isoenzymes for the improvement of organo-specific diagnosis.
abstract: The LDH isoenzymes from mixed granulocytic populations and from homogenates of different organs, as well as alkaline phosphatase from human liver and intestine, were separated and purified by means of chromatography using ion exchangers (DEAE-cellulose and DEAE-Sephadex A50). Comparison of purified LDH isoenzyme chromatograms with the zymograms in agar gel has allowed the determination of the isoenzymatic pattern of the respective tissues and its correlation with the predominant energetic processes. The purified extracts of alkaline phosphate have lead to the characterization of the main molecular forms of the enzyme thus enabling a more precise organo-specific diagnosis.
