Viral RNA Extraction Kit is a fast reagent for the isolation of viral RNA from whole blood, serum, plasma, oropharyngeal swab, and other biological fluids. Carrier RNA has been used in this Kit. Carrier RNA not only enhances precipitation of viral RNA, but also reduces RNA degradation. Experiments can be done in 30-40 minutes, and achieve high-quality viral RNA with no contamination of DNA and proteins. RNA can be applied for RT-PCR, real-time qPCR, Northern blot, Dot blot, poly(A)+ selection, in vitro translation, RNase protect analysis and molecular cloning. In addition, Lysis Buffer VLS is a great storage solution for viral RNA. Viral lysate (add Lysis Buffer VLS to sample based on the volume ratio 3:1 and vortex rigorously) can be stored up to 2 months at -20℃ and half year at-80℃; also the lysate can be stable up for 1 day at 4℃, and 1 week at -20℃ in transportation.
