Received November 20, 1980. A method is proposed to enrich RNA molecules having a 5'-terminal triphosphate group. The method is based upon selective chemical modification of 5'-triphosphate groups by an antigen-containing amine followed by affinity chromatography on an absorbent loaded with antibodies specific to this antigen. A purification factor up to 37 may be achieved.
