Optimal RNA extraction is a key to success for any RT-qPCR experiment. To avoid false positives and background, the complete removal of genomic DNA is another key variable. Ambion® products will simplify your experiments. You can even get RT-qPCR results direct from cells without prior RNA isolation with Ambion® Cells-to-CT™ kits

Eliminate Genomic DNA Contamination
Genomic DNA contamination can lead to false positive RT-PCR results. We offer a variety of Ambion® tools for minimizing genomic DNA contamination from RNA samples prior to RT-PCR. For example, DNA-free™ DNase Treatment and Removal Reagents are designed for removing contaminating DNA from RNA samples and for the removal of DNase after treatment without Proteinase K treatment and organic extraction. In addition, we offer TURBO DNase™ enzyme kits, a hyperactive enzyme engineered from wild-type bovine DNase. The proficiency of TURBO DNase™ enzyme in binding very low concentrations of DNA means that the enzyme is particularly effective in removing trace quantities of DNA contamination. To prevent cross contamination during PCR experiments, we also offer DNAZap™ DNA Degradation Solution and RNase-free barrier pipette tips.
