  • Ribozyme-mediated synthesis of circular RNA
    Patent number: 6210931
    Abstract: Circular RNAs may be synthesized by inserting DNA fragments into a plasmid containing sequences having the capability of spontaneous cleavage and self-circularization. Insertion of the DNA fragments allows RNAs of predetermined size to be constructed. In addition, a two-dimensional polyacrylamide gel electrophoresis system having a second dimension more highly cross-linked than the first dimension permits the separation and analysis as well as the precise sizing of both linear and circular RNAs produced by the synthetic method.
