ABSTRACT:
The present invention is directed to novel methods of synthesizing multiple copies of a target nucleic acid sequence which are autocatalytic (i.e., able to cycle automatically without the need to modify reaction conditions such as temperature, pH, or ionic strength and using the product of one cycle in the next one). In particular, the present invention discloses a method of nucleic acid amplification which is robust and efficient, while reducing the appearance of side-products. The method uses only one primer, the “priming oligonucleotide,” a promoter oligonucleotide modified to prevent polymerase extension from its 3′-terminus and, optionally, a means for terminating a primer extension reaction, to amplify RNA or DNA molecules in vitro, while reducing or substantially eliminating the formation of side-products. The method of the present invention minimizes or substantially eliminates the emergence of side-products, thus providing a high level of specificity. Furthermore, the appearance of side-products can complicate the analysis of the amplification reaction by various molecular detection techniques. The present invention minimizes or substantially eliminates this problem, thus providing an enhanced level of sensitivity.
