Quantification of POWV RNA Levels

Check if the same lab product or an alternative is used in the 5 most similar protocols
Total intracellular RNA was isolated using the RaPure Total RNA Kit (Magen). To analyze the POWV RNA levels in replicon cells, quantitative RT-PCR was performed. In brief, 1 µg total RNA was reverse transcribed using the ReverTra Ace qPCR RT Kit (TOYOBO, FSQ-101) to produce cDNA with random primers. Reactions of qPCR were carried out using the 2× RealStar Green Power Mixture (Genstar, A311) according to the manufacturer’s instructions. The qPCR primers for viral RNA were as follows—POWV: THU-5193 (5′-CGC CCT CAA CAC CAT CAC AAA C-3′) and THU-5194 (5′-TCA ACT CCG TGC TCC TTC AAC C-3′). The sequences of the qPCR primers for GAPDH were described previously (45 (link)). Relative expression levels of the target genes were calculated using the comparative cycle threshold method. All data were normalized relative to GAPDH.

The total RNA was extracted from HCC cells using RaPure Total RNA Kit (Magen, Guangzhou, China). Then, complementary DNA was synthesized using the PrimeScript RT reagent Kit (Takara, Kusatsu, Japan). Quantitative real-time polymerase chain reaction (qRT-PCR) was performed with SYBR Premix ExTaq (Takara) on a LightCycler (Roche, Indianapolis, IN). Conditions for reverse transcription polymerase chain reaction were 30 seconds at 95°C and followed by 40 cycles of 95°C for 5 seconds. The primers were as following: CTSC, forward: 5′-CCAACTGCACCTATCTTGACC-3′ and reverse: 5′-AAGGCAAACCACTTGTAGTCATT-3′; glyceraldehyde 3-phosphate dehydrogenase (GAPDH), forward: 5′-ACAACTTTGGTATCGTGGAAGG-3′ and reverse: 5′-GCCATCACGCCACAGTTTC-3′; TNF-α, forward: 5′-GAGGCCAAGCCCTGGTATG-3′ and reverse: 5′-CGGGCCGATTGATCTCAGC-3′. GAPDH was used as an internal control for semi-quantitation. All qRT-PCR experiments were performed in triplicate.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
