- Abstract
The LDH isoenzymic pattern was studied in platelet cytolysates from man and rabbits, and the two forms of ATP-ase-the Mg++ and the Ca++ activated ones--were assayed in human platelet cytolysates. In man, the platelet LDH zymogram was of the intermediary type. Some of the zymograms presented 4 fractions others 5; in all patterns the H/M subunits ratio was above 1. In rabbits, the platelet LDH zymogram was of the anodal type with only 4 bands; the H/M subunits ratio showed the same variations as in man. Of the two forms of ATP-ase, the Mg++ activated one was dominant in the platelet cytolysates studied.
