WebThe enzyme has been used for an assay to detect the amount of Tf1 RNA that is protected from degradation by the nuclease, Benzonase. The Tf1 element of Schizosaccharomyces pombe is a long terminal repeat-containing retrotransposon that encodes functional protease, reverse transcriptase, and integrase proteins. It has also been used in the … WebThe assay is highly selective for small RNA over rRNA or large messenger RNA (mRNA) (>1,000 bp). Small RNA in pure samples has reproducibly been quantified at levels as low as 0.5 ng in the assay tube. The assay detects all types of small RNA, including microRNA and short interfering RNA (siRNA), both single- and double-stranded.
WebAbstract. We propose a straightforward method to estimate the purity of vesicle preparations by comparing the ratio of nano-vesicle counts to protein concentration, using tools such as the increasingly available NanoSight platform and a colorimetric protein assay such as the BCA-assay. Such an approach is simple enough to apply to every vesicle ... WebIn the presence of chaotropic salt, nucleic acids (NA) bind specifically to the surface of glass fibers pre-packed in the High Pure Filter Tube. Bound nucleic acids are washed, and thereby purified of salts, proteins, and other impurities.
