The invention relates to a composition for stabilizing the total nucleic acids from whole blood, in particular RNA, and to a process for stabilizing the total nucleic acids from whole blood for subsequent isolation and at the same time serves for the disruption of cells so that cellular nucleic acids in the state at contacting the composition, especially at the point of time of blood collection, are released and are maintained stable in respect of quality and concentration and can be isolated subsequently. Therein, the composition is characterized in that it especially prevents the degradation and new synthesis of RNA in whole blood, into which it is mixed. The isolation of RNA by contacting the mixture of the aqueous composition and blood with an adsorption agent can be made directly from the complete mixture of the aqueous composition with blood, i.e. e.g. without precipitation and separation of nucleic acids from the mixture, optionally after a storage, during which the mixture is e.g. transported from the place of blood collection to the place of the analytical process.
