The sample should avoid repeated freezing and thawing, otherwise it will affect the yield and quality of RNA extraction.3. If TRIzon Reagent is found to have precipitates before use, it can be dissolved in a water bath at 56 ℃ for a few minutes.Before the first use, anhydrous ethanol should be added to Buffer RW2 according to the instructions on the reagent bottle label.5. All centrifugation steps should be carried out at room temperature unless otherwise specified, and all operation steps should be carried out quickly.Usage：1. Sample processing1a. Organization: 30-50 mg of tissue is thoroughly ground in liquid nitrogen and 1 mL of TRIzon Reagent is added, or 1 mL of TRIzon Reagent is added to the tissue sample and homogenized.

Centrifuge at 4 ℃ 12000 rpm (~13400 × g) for 10 minutes. At this time, the sample is divided into three layers: the red organic phase, the middle layer, and the upper colorless aqueous phase. RNA is mainly in the upper aqueous phase. Move the upper aqueous phase to a new RNase Free centrifuge tube (provided).5. Add an equal volume of 70% ethanol (prepared without RNase water) to the obtained aqueous solution, invert and mix well.6. Add all the solutions obtained in the previous step to the spin columns RM that have been loaded into the collection tube.
