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.

Vacuum Hydrolysis Tube, 6 mL (Thermo Scientific™)

Thermo Scientific Pierce Vacuum Hydrolysis Tube, 6 mL is a high-quality glass tube designed for heated, acid-based, vacuum hydrolysis of proteins and peptides for amino acid analysis.

Features of Vacuum Hydrolysis Tube, 6 mL:

• Saves 10-18 hours on hydrolysis procedures when combined with 6N HCl (Part No. 24308)
• Provides for hydrolysis in 6 hours when heated at 150°C in a dry block heater (Note: the upper temperature limit of Vacuum Hydrolysis Tubes is 260°C in a block heater but only 110°C in an oven)
• Optimal hydrolysis control when used with Reacti-Therm Dry Block Heating System
• Compatible-fitting are available for use with Thermo Scientific Reacti-Therm Heating Modules

Applications of Vacuum Hydrolysis Tube:
• Protein/peptide hydrolysis
• Sample concentration
• Lyophilization
• Hydrazinolysis

Vacuum Hydrolysis Tubes are precision-designed for use in protein hydrolysis and subsequent analysis of protein and peptide amino acid compositions. The heavy-walled borosilicate glass construction ensures complete compatibility with all commonly used acid hydrolysis reagents. Acid hydrolysis at elevated temperatures, in vacuo, will hydrolyze most proteins and peptides to their amino acid components without significant decomposition.

Vacuum hydrolysis methods commonly use 6N constant boiling hydrochloric acid (HCl), a mixture of HCl and propionic acid, 3N mercaptoethanesulfonic acid or 4N methanesulfonic acid. The constant boiling HCl method uses standard protein hydrolysis at 105 to 110°C for 16 to 24 hours. Using the HCl/propionic acid method, hydrolysis times can be shortened to 15 minutes at 160°C. Tryptophan is easily degraded by acid hydrolysis in 6N HCl. The presence of oxygen, heavy metals and carbohydrates are contributing factors to this degradation. A 22-hour hydrolysis method was developed to improve tryptophan recovery from protein hydrolysis samples by using 3N mercaptoethanesulfonic acid. A second method to improve tryptophan recovery involves hydrolysis at 115°C using 4N methanesulfonic acid.
