Application

TRI Reagent is an improved version of the single-step total RNA isolation reagent developed by Chomczynski. The RNA isolation method based on this reagent is widely used and proven for RNA applications. It is ideal for quick, economical, and efficient isolation of total RNA or the simultaneous isolation of RNA, DNA, and proteins from samples of human, animal, plant, yeast, bacterial, and viral origin.

The reagent has been used for isolating RNA.^[1][2][3] The resulting RNA can be used for Northern blots, mRNA isolation, in vitro translation, RNase protection assay, cloning, and PCR.

Features and Benefits

? Easily scalable RNA isolation
? Works with many sources: human, plant, yeast, bacterial, or viral
? Better yields than traditional guanidine thiocyanate/cesium chloride methods

包裝

25, 100, 200 mL in glass bottle

General description

TRI Reagent is a quick and convenient reagent for use in the simultaneous isolation of RNA, DNA, and protein. Successful isolations from human, animal, plant, yeast, bacterial, and viral samples can be obtained. A convenient single-step liquid phase separation results in the simultaneous isolation of RNA, DNA, and protein. This procedure is an improvement of the single-step method reported by Chomczynski and Sacchi for total RNA isolation. TRI Reagent performs well with large or small amounts of tissue or cells and many samples can be simultaneously extracted.

This product, a mixture of guanidine thiocyanate and phenol in a monophase solution, effectively dissolves DNA, RNA, and protein on homogenization or lysis of tissue sample. After adding chloroform or 1-bromo-3-chloropropane and centrifuging, the mixture separates into 3 phases: an aqueous phase containing the RNA, the interphase containing DNA, and an organic phase containing proteins. Each component can then be isolated after separating the phases. One ml of TRI Reagent is sufficient to isolate RNA, DNA, and protein from 50-100 mg of tissue, 5-10 ′ 106 cells, or 10 cm2 of culture dish surface for cells grown in monolayer.

This is one of the most effective methods for isolating total RNA and can be completed in only 1 hour starting with fresh tissue or cells. The procedure is very effective for isolating RNA molecules of all types from 0.1-15 kb in length. The resulting RNA is intact with little or no contaminating DNA and protein.
