网页A PMA (propidium monoazide) pretreatment protocol, in which PMA is applied directly to membrane filters, was developed for the PCR-based quantification (PMA-qPCR) of viable Legionella pneumophila. Using this method, the amplification of DNA from membrane-damaged L. pneumophila was strongly inhibited
网页2021/05/07 · therefore, in this study, we investigated whether pre-filtration removed humic acid, a pcr inhibitor, and improved the species detection of the edna approach following two methods: 1) edna metabarcoding with amplicon sequencing to investigate the impact of pre-filtration on the detection of fish communities, and 2) species-specific edna detection
网页Polyethersulfone (PES) membrane filters, a nearly perfect filter solution Polyethersulfone (PES) membrane filters are hydrophilic, high flow rate and low non-specific protein adsorptive membranes. These properties make them excellent for the filtration of aqueous solutions as well as variouse solvents and pharmaceutical solutions.
