General description

TRI reagent® also known as TRIzol, is a monophasic solution of phenol and guanidinium isothiocyanate. It has a potential, to simultaneously solubilize biological material and denatures protein. It is widely used for deproteinizing RNA. This improved version of the single-step total RNA isolation reagent developed by Chomczynski allows a quick, economical, and efficient isolation of total RNA from different biological samples. This product is pure (A260/A280 ~1.8) and can be directly used in Northern blotting. Simultaneous isolation of DNA, RNA and proteins is also possible. 1 mL is sufficient for the extraction of 100 mg tissue or 107 cells.

Application

TRI Reagent® has been used for isolating RNA from various types of cells or tissues. It may also be used for processing tissues, cells cultured in monolayer, or cell pellets.
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.

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
