Abstract: The present invention provides a method for preparing a sterilized composition suitable for stabilizing an extracellular nucleic acid population of a biological sample. Also provided are sterilizable compositions, wherein the compositions in sterilized form are suitable for stabilizing an extracellular nucleic acid population of a biological sample. Further useful methods, devices, kits and uses are also provided. Further sterilisable and sterilized compositions described herein are also suitable to stabilize intracellular nucleic acids (e.g. intracellular DNA such as genomic DNA and/or intracellular RNA) and cell characteristics, such as e.g. cell surface proteins and/or the cell morphology.
