Studies on erythrocyte aminolaevulinate dehydratase I. Its purification and possible therapeutic applications

Mostrar todas las versiones(3)

1. 1. A method for purifying human erythrocytes ALA-D, using a mixture of n-butanol and chloroform, which denature hemoglobin, followed by ammonium sulphate fractionation and affinity chromatography yielding a 1600-fold purified enzyme, is described. 2. 2. By oxidation of Sephadex G-25 with NaIO4, a...
