RNA Depletion in Plasmid DNA Extractions with Mag-Bind® TotalPure NGS

Clean Up, Downstream Applications, Product Application / By

Introduction Traditionally, plasmid DNA purification hinges on alkaline lysis. In this method, bacteria, typically E. coli, containing the targeted plasmid DNA are harvested from overnight culture and resuspended in solution. A highly alkaline solution containing a detergent lyses the bacteria cells and denatures both the plasmid and genomic DNA. The addition of a highly acidic

DNA from Saliva Performs Well Downstream, Despite Poor A260/A230 Ratios

Downstream Applications, Product Application / By

The non-invasive nature of sample collection makes saliva an appealing sample type for patients and researchers alike. However, one hindrance to using saliva for genomic analysis is the appearance of low purity in eluates when quantified using absorbance ratios. Here, we discuss the nature of absorbance ratios and contextualize their meaning when analyzing extractions from

DNA Sequencing Could Help Restore Genomic Diversity to at-risk Populations of Pumas in California

Leave a Comment / Environmental, Product Application / By

Introduction The consequences of the expansion of human development have been especially felt in California where human activity has eradicated several apex predators, like the California Grizzly and gray wolf. Unlike these predators, the puma, also called the mountain lion or cougar, has continued to populate the state, though their population is threatened by the continued
