Abstract

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.
