Popis: SUMMARY 1) Patients suffering from malignant melanoma or the associated benign condition of halo naevus excrete a specific melanoma associated protein in their urine. 2) Purification of this protein by gel chromatography, high voltage electrophoresis and salt fractionation gave low yields because of contaminating proteases in the urine. 3) Affinity chromatography of native urine on a column of rabbit anti-melanoma antiserum bound to AH-Sepharose 4B gave a single electrophoretic component in good yield. 4) 3M KCNS and 1 M propionic acid pH 2.5 were equally effective as desorbents. 5) Rechromatography on a dummy column resulted in significant loss of specific protein.
