Abstract:
The present invention provides a method for amplifying a nucleic acid molecule. The method involves mixing an RNA template with a composition having a reverse transcriptase, a DNA polymerase and a RT inhibition reducer. The RT inhibition reducer can be Sso7d, Sac7d, Sac7e, Sso7e, AluI methylase, suramin, a phosphorothioate oligodeoxycytosine, a phosphorothioate oligodeoxyadenine, a phosphorothioate oligodeoxythymine or poly(rA)(dT). The mixing forms a mixture that is incubated under conditions sufficient to synthesize a DNA molecule complementary to all or a portion of the RNA template, thereby amplifying the nucleic acid molecule.
Abstract:
The present invention provides methods and compositions for improving the efficiency of nucleic acid amplification reactions. The invention encompasses hybrid polymerases that show increased processivity over wild type polymerases as well as decreased exonucleases activity. The invention also encompasses methods, compositions and kits for conducting nucleic acid synthesis and amplification reactions in which non-specific amplification of primers is reduced.
Abstract:
In one aspect, compositions and methods for reducing reverse transcriptase (RT) inhibition in RT-PCR are provided. In some embodiments, the RT inhibition reducer is a phosphorothioate oligodeoxycytosine (SdC), phosphorothioate oligodeoxyadenine (SdA), phosphorothioate oligodeoxythymine (SdT), or phosphorothioate oligodeoxyguanosine (SdG).
