Biochemical fractionation
WebBiochemical Fractionation. To fractionate cells, cells washed with an ice cold phosphate saline buffer were treated for 10 min on ice with a hypotonic buffer containing 20 m m Hepes pH 7.2, 10 m m potassium chloride, 1 m m magnesium chloride, 1 m m DTT. After incubation, cells were passed through a Dounce homogenizer equipped with a tight pestle.
