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.
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.
Can frozen blood samples be used with the Tri-Isolate kit? Yes. Place the frozen sample into a 1.5ml micro-centrifuge tube and add 3 volumes of Tri-Isolate reagent and allow the sample to thaw. Incubate an additional 5 minutes at room temp and proceed with rest of protocol.
Can the protocol be altered to accommodate high lipid samples such as brain tissue? Yes. After homogenization, centrifuge the sample at 12,000 – 16,000 x g for 2 minutes to remove insoluble particles. After centrifugation of hi-fat sample, a layer of fat will float on the supernatant. Remove and discard the fatty layer than transfer the supernatant to a new 1.5ml centrifuge tube. Continue with RNA binding step #2.
