Carisa Townsend1, Kiranmai Durvasula1, Julie Baggs1, and Travis Butts1 Omega Bio-tek, Inc, Norcross, GA 30071 Introduction Recent advancements and studies have demonstrated the potential of cfDNA as a universal, non-invasive biomarker in cancer prognosis, diagnosis, and prenatal testing. cfDNA are found in low abundance and in a background of contaminating genomic DNA making it a […]
Carisa Townsend1, Kiranmai Durvasula1, and Travis Butts1 Omega Bio-tek, Inc, Norcross, GA 30071 Introduction With advances in genomics research, personalized medicine, and sequencing-based technologies, there is a necessity for purification of high-quality genomic DNA from large volumes of blood. The rapidly growing landscape of biorepositories that store large amounts of DNA from an enormous number
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
RNA Depletion in Plasmid DNA Extractions with Mag-Bind® TotalPure NGS Read More »
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
