Compared to the two other … Spletpred toliko urami: 12 · We directly confirmed alternative splicing events upon ArgRS knockdown for FGFR3 and PLEKHG5 in HepG2 cells with reverse transcription polymerase chain reaction (RT–PCR) (Extended Data Fig. 7a,b).
Splet11. apr. 2014 · Following exposure to stress at 37°C, 1 μL of each resulting lysate was analyzed directly by one-step RT-qPCR targeting the influenza virus matrix gene; in parallel, total RNA was column ... SpletPolymerase chain reaction, or PCR, is a technique to make many copies of a specific DNA region in vitro (in a test tube rather than an organism). PCR relies on a thermostable DNA polymerase, Taq polymerase, and requires DNA primers designed specifically for the DNA region of interest.
