Mo Bio Laboratories this week launched the RTS DNase kit for removing contaminating genomic DNA from RNA preparations while protecting the RNA samples from damage during the DNase treatment process.

The kit includes the first room-temperature-stable DNase I enzyme, which eliminates concerns over freeze-thaw cycles that may decrease enzymatic activity. The kit also contains a highly specific resin that is used to bind and remove the RTS DNase enzyme and divalent cations from the reaction for optimal qPCR results, Mo Bio said.

Lucigen this week announced the release of Taq98 Hot Start 2X Master Mix.

This new DNA polymerase is ideal for customers seeking to amplify difficult DNA templates, including targets with greater than 70 percent GC content. The product combines Taq polymerase with a unique fusion protein that enhances DNA binding, as well as CleanAmp dNTPs from TriLink Biotechnologies.

The end result, the company said, is a highly robust polymerase in an easy-to-use master mix that avoids primer-dimers and other common PCR problems while amplifying template DNA sequences that are often difficult for competing PCR kits to amplify.
