Extraction of RNA of high quantity and quality is a preliminary step for many investigations in plant molecular biology such as Northern Blot hybridization, mRNA purification, PCR amplification, cDNA synthesis and cDNA library construction (Hu et al., 2002).However, to isolate RNA from some plant tissues is manifestly difficult due to the presence of high amounts …
Read OnFirst, add an equal volume of ethanol (1:1) to the lysed sample in TRIzol® and mix. Bind RNA to the silica-based column, wash the column, then elute RNA (Figure 2). Figure 2. No more precision pipetting. With Direct-zol, just bind, wash, and elute the RNA. The Direct-zol RNA kit includes DNase I, so you can also rapidly remove contaminating DNA.
Read OnConcerning the appropriate amount of milk for RNA extraction, several volumes are proposed, with 150 ml being the most suitable in terms of yield and quality (Mura et al., 2013). In our analysis ...
Read OnSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the etiologic agent of the COVID-19 pandemic. Although other diagnostic methods have been introduced, detection of viral genes on oro- and nasopharyngeal swabs by reverse-transcription real time-PCR (rRT-PCR) assays is still the gold standard. Efficient viral RNA extraction is a ...
Read On• The first step in RNA extraction is to break down the cells or tissue so that the nucleic acids are released from the cells. • Homogenization Tissue: mortar and pestle Cells: repetitive pipetting (resuspend) • RNA extraction methods use a powerful chaotropic salt solution. This ' lysis solution ' rapidly disrupts cells without

Read OnHeating RNA in presence of divalent cations leads to hydrolysis of RNA. EDTA chelates divalent cations, thus protecting RNA from hydrolysis. Optional: You can proceed to determine concentration of RNA and check the quality by gel electrophoresis. Storage: RNA can be stored at -20°C (for few months) or – 80°C (for years).
Read OnProtocol for total RNA extraction from Cells and Tissues Using TRIzol. 1. Cell Lysis. If you are isolating RNA from tissues, you will need to homogenize the sample first in 1 ml of TRIzol reagent per 50 to 100 mg of tissue using a homogenizer. The sample volume should not exceed 10% of the TRIzol volume.
Read OnDNA/RNA extraction can be divided into two steps: cell lysis and purification. Cell lysis is the process of destroying the cell structure of the sample, thus making the DNA in the sample free in the pyrolysis system. Purification is the process of completely separating DNA from other components in the lysis system, such as protein, salt and ...
