A rapid procedure which is based on combined ion-exchange chromatography and solubility was established for determination of the activity of ganglioside synthases and cerebroside sulfotransferase. The procedure consists of selective elution of radiolabeled reaction products (acidic glycolipids) freed from labeled precursors and breakdown products on a DEAE-Sephadex column and of direct radioassay of the products in the eluate. Monosialogangliosides were eluted from the column with 40 mm ammonium acetate (AcONH4) in methanol, cerebroside sulfate with 90 mm AcONH4in methanol, and disialogangliosides with 40 mm AcONH4in isopropanol/n-hexane/water (55/20/19, v/v/v). The established procedure is simple, reproducible, and economical. Using rat Golgi membrane as enzyme source the recovery rate of the products was over 95%.
