Before planting, the seed potatoes should be processed through four steps: seed selection, sun-breeding, soaking and cutting. Among these four links, cutting is closely related to mechanical sowing, and must be cut according to the standard before sowing. The potato cups of the three seeders are the same size. Therefore, it is required that the potato seed pieces have the same size, and the 1500 times high potassium perchlorate solution is prepared before cutting. Used for soaking and sterilizing of cutting and cutting boards. The weight of the seed is kept at around 50 grams. The seed potato is large, the bud eye is less, the seed potato is small, and the bud eye is more. Leave 2 to 4 full buds on each seed. The size of the dicing should be controlled within 3.5 to 4.5 cm. The seed potato should be immersed in 75% rare earth dryland treasure 1000 times solution for 30 minutes. It can not only sterilize and prevent corrosion, but also a plant growth regulator, which can promote the germination and rooting of potato seed potatoes and enhance drought resistance.

The RNA purification kit is used to purify and recover RNA molecules transcribed in vitro and total RNA extracted from various materials, which can effectively remove contaminating impurities in RNA samples. The recovery rate of this product can reach 80%, and the OD260/OD280 ratio of the obtained RNA is generally about 2.0, which can be directly used in subsequent sensitive experiments (such as microarray analysis, fluorescence RT-PCR, etc.). With the deepening of transcriptomics, the complexity of RNA types, expression regulation and functions is far beyond our imagination.

Removing ribosomal RNAs that account for more than 80% helps to focus sequencing on less abundant but informative RNAs. At present, the removal of rRNA is mainly through the combined use of probe and RNase H. The processed RNA will be mixed with many digestion products, enzymes and ions, which is not conducive to the subsequent construction of RNA library. Take the Columnar RNA Purification Kit as an example. Trizol is a ready-to-use reagent that can be used to purify total RNA from tissues and cells. This is a single-phase solution of phenol and guanidine isothiocyanate that facilitates lysis of tissues and cells, inhibiting RNases to maintain RNA integrity.
