Product Information

TRI Reagent® BD is designed for use with whole blood and plasma. Fifty milliliters is sufficient to process 65 samples of 0.25 ml each.


TRI Reagent® is a patented reagent for the isolation of total RNA or for the simultaneous isolation of RNA, DNA and proteins. The reagent is an improved version of the popular single-step method for total RNA isolation (1,2,3). It is a monophase solution containing phenol and guanidine thiocyanate. TRI Reagent® provides a reliable, cost effective and efficient method of RNA isolation. TRI Reagent® allows for a comprehensive analysis of gene expression in a variety of samples of human, animal, plant, yeast, bacterial and viral origin. RNA isolation is complete in less than one hour, and DNA and protein isolations in less than three hours. Three versions of TRI Reagent® are available, each designed for optimal isolation efficiency from certain types of samples.
