The PureLink Viral RNA/DNA Mini Kit provides a rapid and efficient method to simultaneously purify viral RNA/DNA from fresh or frozen cell-free biological fluids (plasma, serum, cerebrospinal fluid) and cell culture supernatants. The kit is specifically designed to isolate high-quality viral nucleic acids from a variety of RNA and DNA viruses within 45 minutes using low elution volumes that allow sensitive downstream analysis. The purified viral RNA/DNA is devoid of proteins and nucleases and is suitable for use in downstream applications that allow viral detection and genotyping.

The PureLink Viral Mini Kit has been used to purify viral dsDNA from orthopoxviruses including cowpox virus, variola virus, monkeypox virus, vaccinia virus, and HERV.

The PureLink Viral RNA/DNA Mini Kit provides the following advantages:
• Rapid and efficient purification of high-quality viral nucleic acid using spin column-based centrifugation with no sample cross-contamination
• Specifically designed to purify viral RNA and DNA from ≤500 μL cell-free samples within 45 min
• Ability to elute viral nucleic acids in low elution volumes of 10–50 μL to allow sensitive downstream analysis

For Research Use Only. Not for use in diagnostic procedures.

Frequently asked questions (FAQs)

Are additional wash tubes available for the PureLink Viral RNA/DNA kits if I do not want to use the wash columns twice?

Yes, the Cat. No. for 100 wash tubes is 12282-100.

What is the stability of the Proteinase K in the PureLink Viral RNA/DNA kits?

The Proteinase K solution is stable for 1 year when stored at room temperature. For long-term storage (>1 year) or if room temperature is >25 degrees C, store the Proteinase K solution at 4 degrees C.

What is the difference between serum and plasma?

Plasma is the liquid portion of the blood that is separated from the blood cells by centrifugation. One of the characteristics of plasma is that it clots easily, which is important for hemophiliacs needing a transfusion but is a nuisance in most other applications. By agitating the plasma, one can precipitate the clotting factors as a large clot, and the leftover fluid is called serum. In other words, serum plus clotting factors is plasma, and clotted plasma yields serum.

What is the stability of the carrier RNA in the PureLink Viral RNA/DNA kit, both lyophilized and in solution?

The tRNA is stable for over one year. There was no significant difference in qRT-PCR results with tRNA stored for 10 days at ‘20 degrees C or 42 degrees C. The lyophilized tRNA is stable at ‘20 degrees C, room temperature, 37 degrees C, and 45 degrees C for up to 1 month.

Do I need to use the carrier RNA in the PureLink Viral RNA/DNA kit?

The carrier RNA is tRNA and it may not be necessary. We have tested without the tRNA and obtained excellent results. The tRNA provides a substrate for RNases in the sample to protect the viral RNA until the virus is lysed. You may want to scale down the amount of carrier RNA or leave it out. However, you should validate it in your application to make sure you get the same results as when you include it.
