Rapid extraction of total RNA from Eucalyptus leaves is difficult due to the high content of polyphenolics and polysaccharides. A rapid and simple method was developed by using an extraction buffer containing sodium isoascorbate at a concentration of 500 mM. This method consisted of one or two chloroform extractions, one acid guanidium-phenol-chloroform extraction, and isopropanol precipitation...

Detection of bacterial gene expression in soil emerged in the early 1990s and provided information on bacterial responses in their original soil environments. As a key procedure in the detection, extraction of bacterial RNA from soil has attracted much interest, and many methods of soil RNA extraction have been reported in the past 20 years. In addition to various RT-PCR-based technologies, new...

Prostate cancer antigen 3 (PCA3) is a non-coding RNA fragment that is overexpressed in prostate cancer cells. However, the clinical applications of PCA3 are highly limited due to the instability of RNA and the lack of reliable and efficient RNA extraction and purification methods. Thus, in the present study, we compared three different methods of RNA extraction to further confirm the higher yie...

The efficiency of extraction methods for hepatitis A virus (HAV) RNA in clinical samples is of great importance for molecular diagnosis, especially in regions endemic for HAV, such as Brazil. We compared the efficiency of four different extraction techniques in serum and stool samples for the detection of hepatitis A virus by reverse transcription PCR (RT-PCR). We used PCR to analyse serum and ...

Analyses of nucleic acids (DNA and RNA) have become a staple tool for botanists to answer questions across wide variety disciplines, ranging from population genetics biogeography, ecology, development, microbiology, physiology, phylogenetics. The rise “next-generation” or “high-throughput” sequencing in particular has resulted reduced costs an explosion the number botanical studies using DNA RN...

Knowing when, and to what extent co-extracted inhibitors interfere with molecular RNA diagnostic assays is of utmost importance. The QIAamp Viral RNA Mini Kit (A); MagNA Pure LC2.0 Automatic extractor (B); KingFisher (C); and NucliSENS EasyMag (D) RNA extraction systems were evaluated for extraction efficiency and co-purification of inhibitors from stool suspensions. Real-Time Reverse Transcrip...

Extraction of high-quality mRNA from Cryptosporidium parvum is a key step in PCR detection of viable oocysts in environmental samples. Current methods for monitoring oocysts are limited to water samples; therefore, the goal of this study was to develop a rapid and sensitive procedure for Cryptosporidium detection in soil samples. The efficiencies of five RNA extraction methods were compared (mR...

BACKGROUND RNA from sorted cell populations is crucial in many instances. We therefore compared four current protocols for RNA isolation, with regard to mRNA yield and purity. Moreover, we examined the effects on RNA recovery caused by different storage reagents. METHODS Small populations of K562 cells or PMBC were sorted into the lysing reagent and subjected to RNA extraction, employing eith...

We explore the possibility to precipitate and extract DNA, or RNA using an active water/ethanol Janus droplet. The droplet is initially formed by a single made of mixture in oil/surfactant solution. This self-propels absorbs surfactant molecules, advection, while moving oily phase. absorption leads phase separation formation water-rich leading ethanol-rich trailing employ this method RNA, DNA/R...
