IBI Tri-Isolate is a phenol and guanidine isothiocyanate plus spin column system for convenient purification of high quality total RNA from a variety of samples including cultured cells, tissue, body fluids, bacteria, and plant tissue

IBI Tri-Isolate is tested on a lot-to-lot basis. 10 µL from a 50 µL eluate of purified RNA is analyzed by electrophoresis on a 0.8% agarose gel.

Initially, samples are homogenized in IBI Isolate Reagent without chloroform phase separation or isopropanol RNA precipitation. Following sample homogenization, simply bind, wash, and elute the high quality, total RNA in RNase-free water. The purified RNA can be used in a variety of downstream applications, including cDNA library construction, cloning, RT-PCR (End-point), Real-Time PCR, nuclease protection assays, northern blotting.
