    摘要: Stabilized reverse transcriptase fusion proteins including a thermostable reverse transcriptase connected to a stabilizer protein are described. Attaching the stabilizer protein to the thermostable reverse transcriptase stabilizes the fusion protein and can aid in its purification, provide increased solubility, allow for longer storage, or allow the fusion protein to be used under more rigorous conditions such as higher temperature. The stabilized reverse transcriptase fusion protein can also include a linker between the stabilizer protein and the thermostable reverse transcriptase. The stabilized reverse transcriptase fusion proteins are suitable for use in nucleic acid amplification methods such as the reverse transcription polymerase chain reaction and other applications involving cDNA synthesis.

    摘要: A method of preparing a DNA copy of a target polynucleotide using template switching is described. The method includes mixing a double stranded template/primer substrate made up of a DNA primer oligonucleotide associated with a complementary oligonucleotide template strand with a target polynucleotide in a reaction medium and adding a suitable amount of a non-retroviral reverse transcriptase to the reaction medium to extend the DNA primer oligonucleotide from its 3′ end to provide a DNA copy polynucleotide. The DNA copy polynucleotide includes a complementary target DNA polynucleotide that is synthesized using the target polynucleotide as a template. Methods of adding nucleotides to the double stranded template/primer substrate are also described. The method can be used to facilitate detection, PCR amplification, cloning, and determination of RNA and DNA sequences.
