[Detection methods for retroviruses and reverse transcriptase: commentary].

Retroviruses are often used as a carrier for expression of target protein or chimeric target gene. Although non-infectious viruses are selected in the laboratory, it does not exclude harms form these viruses. The monitoring and detection of retroviruses has a very important significance. Reverse transcriptase activity is an important indicator of retrovirus replication. Herein, methods for detection of retroviruses and reverse transcriptase are reviewed for further research references.
