NASBA Method
•eNucleic Acid Sequence-Based Amplification (NASBA)
•E used to amplify target RNA
•E employs three enzymes:
•]reverse transcriptase:
•]ribonuclease H:
•]T7 RNA polymerase:
•-makes complementary DNA strand from RNA and it serves as template for rurther replication
•-degrades RNA to allow for a complete-double stranded DNA
•-produces multiple copies of RNA from DNA template
•clinical application:
•detection of viral RNA
