title: Isozymes of amino acid naphthylamidase in chronic meyloid leukaemia and erythroleukaemia.
abstract: Isozymes of amino acid naphthylamidase were investigated in 11 patients with chronic myeloid leukaemia (CML) and 1 patient with erythroleukaemia. Two isozymes were found in all cases (isozymes A and C) which also occur in normal granulocytes. An isozyme with intermediate mobility appeared in all the patients in two main forms (isozymes BF and BS), which both differed from the isozyme B found in normal granulocytes. This may therefore support the diagnosis. In 3 patients a shift occurred between isozymes BF and BS, the possible significance of which is discussed.
