Photoactive stain covalently binds to nucleic acids in solution and in cells with damaged membranes.
Used to footprint drug binding sites on DNA, detect non-viable cells, identify ethidium binding sites on DNA and tRNA, and selectively inactivate gene expression.
Cold atmospheric-gaseous plasma (CAP) is an emerging non-thermal technology for decontamination of foodborne bacterial and viral pathogens. We obtained a >5 log10 reduction in the titer (TCID50) of feline calicivirus (FCV) on stainless steel discs and Romaine lettuce leaves after
Water science and technology : a journal of the International Association on Water Pollution Research, 63(3), 502-507 (2011-02-01)
A method was developed for discriminating damaged viruses or naked viral RNA from intact viruses by ethidium monoazide (EMA) treatment before RT-PCR. The applied EMA treatment consisted of three steps: (1) EMA dose, (2) exposure to light, and (3) additional

To optimize ethidium monoazide (EMA) coupled with real-time quantitative PCR (qPCR) and to evaluate its environmental applicability on quantifying viable legionellae in water and biofilm of cooling towers and hot water systems. EMA (0.9-45.5 microg ml(-1)) and propidium monoazide (PMA
DNA-based methodology for the identification and detection of specific bacteria in dental plaque offers advantages over culturing techniques. One drawback of current molecular techniques like real-time quantitative polymerase chain reaction (RT-QPCR) is that they are not able to distinguish between
Cancer treatments have substantially improved childhood cancer survival but are accompanied by long-term complications, notably chronic inflammatory diseases. We hypothesize that cancer treatments could lead to long-term epigenetic changes in immune cells, resulting in increased prevalence of inflammatory diseases in
