Eine reverse Transkriptase (RT) ist ein Enzym, das zur Erzeugung von komplementärer DNA (cDNA) aus einer RNA- Matrize verwendet wird, ein Prozess, der als reverse Transkription bezeichnet wird .Reverse Transkriptasen werden von bestimmten Viren wie HIV und dem Hepatitis B-Virus verwendet, um ihre Genome zu replizieren, von mobilen genetischen Retrotransposon -Elementen, um sich im Wirtsgenom. Reverse-Transkriptase-Inhibitoren sind Wirkstoffe mit antiviralen Eigenschaften gegen HI-Viren (HIV). Sie werden in Kombination mit anderen AIDS-Medikamenten zur Behandlung einer HIV-Infektion eingesetzt. Die Effekte beruhen auf der Hemmung des Enzyms Reverse Transkriptase, welches bei der Vermehrung der Viren eine wichtige Rolle spielt, indem es die virale RNA in DNA überschreibt. Innerhalb. affect reverse transcription efficiency, various inhibitors were added to total HeLa RNA prior to the oligo(dT) 20 annealing step. Concentrations indicated in Figure 1 are the final concentrations of inhibitors in complete reverse transcription reactions. Reverse transcription with SuperScript IV RT, SuperScript III RT, and six other RTs (P, T, BR, Q, BL, and N) from other suppliers, followed. While reverse transcription (RT) is a powerful tool for RNA analysis, the time needed for a reverse transcription reaction can take 15-80 minutes, depending on the procedure used and the size of the cDNA. To test if 80 minutes were necessary for the GoScript™ Reverse Transcription Mixes, three different reverse transcription reaction times (15, 30 and 80 minutes) were tested using the. Reverse transcriptase is commonly used in research to apply the polymerase chain reaction technique to RNA in a technique called reverse transcription polymerase chain reaction (RT-PCR). The classical PCR technique can be applied only to DNA strands, but, with the help of reverse transcriptase, RNA can be transcribed into DNA, thus making PCR analysis of RNA molecules possible
