TriRNA Pure Kit (TRP050/TRP100/TRP200)

RNA Extraction/Tri RNA

The TriRNA Pure Kit is a spin column system for purification of high-quality total RNA from a variety of samples. Initially, samples are homogenized in TRIzol® Reagent, GENEzol™ Reagent or other phenol, guanidine isothiocyanate reagents. Chloroform phase separation or isopropanol RNA precipitation is not required. Following sample homogenization, simply bind, wash and elute the high-quality, total RNA in RNase-free Water and use in a variety of sensitive downstream applications.

QUALITY CONTROL

The TriRNA Pure Kit is tested on a lot-to-lot basis according to Geneaid’s ISO-certified quality management system. An Escherichia coli (1 × 109) culture (OD600=1.3, 1 ml) is harvested by centrifugation at 16,000 x g for 2 minutes, followed by GENEzol™ Reagent homogenization. RNA is then purified using a spin column procedure. 10 µl from a 50 µl eluate of purified RNA is analyzed by electrophoresis on a 0.8% agarose gel.

Figure 1 .RNA was purified using the TriRNA Pure Kit in parallel to the similar product from competitor Z. 5x105 HeLa cells were homogenized using GENEzol™ Reagent and competitor Z tri reagent. RNA was then purified using the corresponing kits spin column procedure. 10 µl from a 50 µl eluate of purified RNA was analyzed by electrophoresis on a 0.8% agarose gel.

Table 2 .RNA was purified using the TriRNA Pure Kit. RNA from 200 µl of whole human blood (3 donors) was initally homogenized using GENEzol™ Reagent. RNA was then purified using a spin column procedure. 10 µl from each 35 µl eluate of purified RNA was analyzed by electrophoresis on a 0.8% agarose gel.
