PureLink™ Viral Collection Tubes (Invitrogen™)

The PureLink® Viral RNA/DNA Mini Kit is a nucleic acid purification system designed for fast and easy isolation of viral RNA or DNA from cell-free samples, such as serum, plasma, and cerebrospinal fluid. Starting sample volumes can be as high as 500 µl and elution volumes as low as 10 µl, allowing for a 50-fold concentration of nucleic acids. The higher target concentration obtained using the PureLink® Viral RNA/ DNA Mini Kit provides greater sensitivity and accuracy in downstream detection procedures such as real-time PCR or endpoint analysis. Specially formulated buffers enable the purification of RNA or DNA, allowing one system to be used for all your virus extraction samples. In addition, the kit provides sufficient quantities of lysis buffer to address large starting sample volumes.

• Yields highly concentrated viral nucleic acids for greater sensitivity in detection - start with 500 µl of sample and elute in just 10 µl volume
• One kit provides a complete solution for virus extraction - both RNA and DNA viruses can be extracted and concentrated
• Spin column technology - achieve fast and easy purification with excellent reproducibility (Figure 1)
• Produces high-quality DNA and RNA - ideal for downstream applications such as real-time PCR and endpoint analysis
Ct values were consistently lower for samples prepared with the PureLink® Viral RNA/DNA Mini Kit (Figure 2), indicating greater sensitivity.

In addition, the quantitation was accurate down to 20 pfu compared to samples prepared with the kit from supplier Q, which leveled off at 200 pfu. Results indicate an improvement in the recovery of viral RNA as well as greater overall consistency of quantitative amplification.

Lower Ct values were obtained with DNA prepared with the PureLink ™ Viral RNA/DNA Mini Kit as compared to those obtained using the kit from supplier Q (Figure 3), indicating greater sensitivity of detection of viral DNA. The data demonstrate that the PureLink® Viral RNA/DNA Mini Kit can recover DNA down to 20 pfu at significantly lower Ct values compared to the competitor’s kit.

The PureLink® Viral RNA/DNA Mini Kit yielded target molecules of consistently lower Ct values compared to the EZ1 Kit; in some cases as much as 4 cycles earlier (Figure 4). The arrows indicate samples that failed to produce a Ct value. In total, 14 out of 48 samples failed to produce a Ct when processed on the BioRobot EZ1 (29%), while the PureLink® Viral RNA/DNA Kit failed to provide a Ct value in only 3 samples (6%), of which both replicates extracted with the EZ1 Kit also failed to produce a Ct value.

For enhanced viral RNA or DNA detection, the PureLink® Viral RNA/DNA Mini Kit has been demonstrated to give lower Ct values and increased nucleic acid recovery when compared to competitor products using volumes recommended by the supplier. The flexibility of the PureLink® Viral RNA/DNA Mini Kit with respect to sample volume, elution volume, and virus type makes it the best solution for purifying viral RNA or DNA.

Stored as directed, the kit is stable for 1 year.

Invitrogen™ Phasemaker™ Tubes (Invitrogen™)

Invitrogen™ Phasemaker™ Tubes contain a thick liquid polymer that separates and completely isolates the upper aqueous phase of a TRIzol® Reagent mix from the organic phase underneath, greatly simplifying removal of the upper phase containing the RNA.

• Pre-dispensed, 2 mL tubes
• Exclusively for RNA extraction
• For use with TRIzol Reagent, TRIzol® LS Reagent, and TRIzol® Plus Purification Kit only
• Simplifies removal of aqueous phase
• Helps increase RNA yield up to 30%
• Does not interfere with downstream experiments

The polymer in Phasemaker Tubes is heavier than the aqueous phase of the TRIzol Reagent mix, but lighter than the organic phase, so after centrifugation it positions itself between these two layers. As a thick polymer, it creates a tight seal between the two phases, easing removal of the aqueous phase and helping to reduce the risk of carrying over contaminants from the organic layer, thereby increasing RNA recovery up to 30%.

The polymer in the Phasemaker Tubes is inert and does not interfere with standard RNA applications. Isolated RNA can be used in RT-PCR, Northern blot analysis, dot blot hybridization, poly(A)+ selection, in vitro translation, RNase protection assay, and molecular cloning.

Phasemaker Tubes accommodate RNA extraction using TRIzol Reagent, TRIzol LS Reagent, and TRIzol Plus Purification Kit only. They are not recommended for use with other organic reagents as the density of those reagents might not be suitable. Phasemaker Tubes are not for use in DNA or protein isolation, but are intended for RNA extraction only.

Phasemaker Tubes work with fresh or frozen samples, including tissue and blood. They also work with samples previously treated with RNAlater™ RNA stabilization solution. Phasemaker Tubes are already pre-dispensed; the tube size is 2 mL.
