Abstract: The present invention provides a material for separating an analyte from an undesired constituent, which material comprises a solid phase and a coating, wherein the solid phase is capable of binding the undesired constituent, and wherein the coating covers the exposed surface of the solid phase to an extent that any binding of the solid phase to the analyte is impeded. A method for preparing the material, and uses of the material for separating an analyte from an undesired constituent are also provided.

Abstract: Provided is a preparative method for isolating RNA comprising an oligo-or polynucleotide from a sample, which method comprises: (a) treating the sample with a reactant capable of covalently modifying the 2?-OH position of the ribose rings of the RNA under conditions so that a proportion of the 2?-OH positions of the ribose rings bear a substituent; and (b) preparing isolated RNA therefrom by separating material containing the substituent from the sample on the basis of a property of the substituent.
Abstract: Provided is a polynucleotide comprising mRNA, rRNA or viral RNA, comprising ribose rings that are covalently modified at the 2?-OH position. Further provided are methods for producing a double-stranded oligo- or polynucleotide from a template comprising an oligo- or polyribonucleotide, a proportion of the ribose rings of which are covalently modified at the 2?-OH position to bear a substituent which enables replication of the template by the nucleic acid polymerase.
