What is the difference between RNeasy Plus and RNeasy plus?
While the classic RNeasy Plus Kit contains gDNA eliminator columns, the RNeasy Plus Universal Kit contains a gDNA eliminator solution.
How does RNeasy mini kit work?
RNeasy technology simplifies total RNA isolation from cells, tissues and yeast by combining the stringency of guanidine-isothiocyanate lysis with the speed and purity of silica-membrane purification. RNeasy Kits provide the highest-quality RNA with minimum copurification of DNA.
What is the difference between RNeasy micro and mini kit?
The RNeasy Plus Micro Kit is specially designed for limited amounts of samples and isolates up to 45 µg pure total RNA The RNeasy Plus Mini Kit purifies up to 100 µg total RNA (>200 nt) from a single extraction with efficient gDNA removal.
How is ethanol removed from RNA?
After you have aspirated 95% EtOH, centrifuge again briefly, and aspirate the remaining ethanol. Then leave the open tubes at room temperature for a short while (5-10 min) to evaporate the residual ethanol (but do not overdry!!!), and then dissolve your RNA in TE or RNAse-free H2O.
How do you get rid of phenol in RNA?
Removing phenol contamination from total RNA – (Apr/01/2009 )
- Remove Media.
- Add 1 ml Trizol/well (for 35 mm plate)
- Shake for 5 min at RT in Plate.
- Triturate 6X, transfer to fresh tube.
- Add 200 ul Chloroform/well.
- Shake 20x.
- Incubate at RT for 2 min.
- Spin at 11,900 rpm for 10 min at 4°C.
What is RLT buffer?
Buffer RLT is a lysis buffer for lysing cells and tissues prior to RNA isolation and simultaneous RNA/DNA/Protein isolation. When following RNeasy Plus or AllPrep DNA/RNA procedures, Buffer RLT Plus should be used.
What is in RLT buffer?
Buffer RLT comprises of guanidinium isothiocyanate or guanidinium thiocyanate, beside known to effectively lyse cell for RNA/ DNA extraction (additionally, to denature RNase enzymes and DNase enzymes), guanidinium thiocyanate is commonly used as a nucleic acid protector.
What is an RW1 buffer?
Buffer RW1 is a proprietary component of RNeasy Kits. Buffer RW1 contains a guanidine salt, as well as ethanol, and is used as a stringent washing buffer that efficiently removes biomolecules such as carbohydrates, proteins, fatty acids etc., that are non-specifically bound to the silica membrane.
What can I resuspend RNA in?
Centrifuge the RNA and resuspend in an appropriate RNase-free buffer before use. RNA can be dried briefly at +37°C or in a vacuum oven.
How can phenol contamination be removed?
To remove phenol contaminant you should to wash twice with cloroform before preciptation. To avoid salt contaminants try to preciptate only with isopropanol. I would suggest to do an isopropanol precipitation (1:1) followed by a wash in 70% EtOH.
