    • The present invention relates to a primer and a probe that are specific to genes of the new influenza A virus subtype H1N1 (2009 H1N1 influenza virus), and to a method for diagnosing the new influenza A virus subtype H1N1 using the primer and probe. More specifically, the present invention relates to a primer for simultaneously diagnosing genes of the new influenza A virus subtype H1N1 through a polymerase chain reaction, a diagnosis kit including an internal control and the primer, and a method for diagnosis using the kit. By means of the primer and probe of the present invention, the new influenza A virus subtype H1N1 can be rapidly and accurately detected without a cross reaction with existing human body influenza A virus subtype H1N1. Also, a dried kit having improved storage stability can be produced so that a user is not required to be highly skilled.

    • The present invention relates to reverse transcriptase with improved thermostability and more specifically, to mutant reverse transcriptase with improved thermostability which is obtained by substituting more than one amino acid in the amino acid sequence of M-MLV derived transcriptase of sequence number 1 which is selected from glutamine (Q63) in 63^th of the amino acid sequence, lysine (K264) in 264^th of the amino acid sequence, lysine (K295) in 295^th of the amino acid sequence, threonine (T306) in 306^th of the amino acid sequence, glutamic acid (E346) in 346^th of the amino acid sequence, proline (P408) in 408^th of the amino acid sequence, histidine (H438) in 438^th of the amino acid sequence, and asparagine (N454) in 454^th of the amino acid sequence with another amino acid. The mutant reverse transcriptase has excellent thermostability compared to wild-type reverse transcriptase, and offers stable reverse transcription activity for users to obtain cDNA when the users cannot effectively obtain reverse transcription results due to the structural interference of specific RNA capable of forming a stable secondary structure at a high temperature.
