Sep 16, 2024 · In most nucleic acid extraction kits, cells are lysed with chaotropic salts and enzymes. Nucleic acid is bound to a silica membrane spin column. Bound nucleic acid is washed with ethanol and chaotropic salts to further purify it. A dry spin removes excess ethanol, and the nucleic acid sample is eluted into a buffer solution or pure water.
Optimized RNA isolation – even from difficult samples. When purifying RNA, it is critical to use an optimized method for your sample type. Our trusted RNA extraction kits ensure high yields of high-quality RNA free of contaminants and inhibitors. Streamlined protocols with optimized RNA extraction reagents simplify handling and are optimized ...
The purpose of RNA extraction is to obtain high-quality purified RNA from biological samples for transcriptomic analysis for applications such as sequencing, transcriptome analysis, and infectious pathogen testing. Obtaining high-quality RNA is the first, and often the most critical, step in performing many RNA-based molecular techniques, such ...
The spin column extraction method This is a solid phase extraction technique to bind and isolate RNA within filter-based spin columns. These spin columns utilize membranes that contain silica or glass fiber to bind nucleic acids. Samples are lysed in a buffered solution containing RNase inhibitors and a high concentration of chaotropic salt.
The Monarch RNA Total Miniprep Kit is a universal kit for RNA extraction and purification from a wide variety of cell types and tissues, including blood, saliva, FFPE, cultured cells, viral, and tough-to-lyse samples (including plant, bacterial and yeast). The kit includes a protection reagent for sample storage and lysis, Proteinase K for ...
Mar 20, 2020 · The only difference was that each technical replicate had their RNA extracted by one of three methods: classic hot acid phenol (Phenol Method), a silica-based column kit (RNeasy Method) and a guanidinium-phenol (TRIzol)-based kit (Direct-zol Method) (Fig. 1). RNA isolated via the Phenol method was subsequently “cleaned” with a Qiagen RNeasy ...

Column-based RNA extraction kits employ a unique Zymo-Spin™-column technology that can be used in a microcentrifuge for purifying high-quality RNA. The RNA is then free of inhibitors and ready for downstream applications. The column-based RNA extraction kits can yield 10 µg, 50 µg, 100 µg, or 1 mg RNA. Magnetic bead-based RNA extraction ...
