title: [Extraction of native preparations of mRNP-particles from the nuclei of kidney bean cells].
abstract: A soft technique is suggested for extracting the mRNP-particles from nuclei. It is based on the incubation of nuclei with ATP. Advantages of the technique, as compared with other described in literature, are as follows: contamination-free mRNP preparations without any DNP fragments are more homogeneous in respect to the CsCl gradient buoyant density and a higher percentage of poly(A)+-mRNP in the total quantity of RNP extracted from nuclei.
