| 摘要 |
The present invention relates to a method for synthesizing a cDNA in a sample in an enzymatic reaction, characterized in that the method comprises the steps: simultaneously providing of a first enzyme with polyadenylation activity, a second enzyme with reverse transcriptase activity, a buffer, at least one ribonucleotide, at least one deoxyribonucleotide, an anchor oligonucleotide, adding of a sample comprising a ribonucleic acid and incubating the agents from the preceding steps in one or more temperature steps, which are selected so that the first enzyme and the second enzyme display activity, characterized in that additionally an amplification takes place in the same reaction mixture. The invention relates further to a reaction mixture comprising a first enzyme with polyadenylation activity, a second enzyme with reverse transcriptase activity, optionally a buffer, optionally at least one ribonucleotide, optionally at least one deoxyribonucleotide, optionally an anchor oligonucleotide and an enzyme with DNA synthesis activity.
