RAA uses a novel RNA substrate tagged with a fluorescent reporter molecule (fluor) on one end and a quencher on the other. In the absence of RNases, the physical proximity of the quencher dampens fluorescence from the fluor to extremely low levels. When RNases are present, however, the RNA substrate is cleaved, and the fluor and quencher are spatially separated in solution. This causes the fluor to emit a bright green signal when excited by light of the appropriate wavelength. Fluorescence can be readily detected with a fluorometer. Since the fluorescence of the RAA Substrate increases over time when RNase activity is present, results monitored with a fluorometer can be evaluated kinetically. The sequence of the RAA Substrate has been carefully optimized to detect several RNases, including RNase A, RNase T1, RNase I, micrococcal nuclease, S1 nuclease, mung bean nuclease, and Benzonase.

RNase activity in a convenient and sensitive fluorimetric assay that delivers results in real time. Great for Quality Testing for RNase contamination of materials and supplies.
Q-PAGE™ TGN (Tris-Glycine Novel) Precast Gels are ready-to-use acrylamide gels for SDS-PAGE running in Tris-Glycine buffer system. With unique formula, Q-PAGE™ TGN Precast Gels perform enhanced speed, better separation, and longer shelf life as compared with conventional Laemmli Tris-HCl gels. The protein migration patterns in Q-PAGE™ TGN series, however, are similar with typical Laemmli Tris-HCl gels, and thus Q-PAGE™ TGN Precast Gels are compatible to traditional SDS-PAGE and subsequent analyses.
Q-PAGE™ TGN Precast Gels are available in gradient (4 to 15%) and fixed (10%) concentrations of polyacrylamide in 12- and 15-well formats. Two available cassette sizes, Mini (10 x 8.3 cm) and Midi (10 x 10 cm), are compatible with most popular protein electrophoresis systems. Q-PAGE™ Mini (QP4XXX) Gels are suitable for Bio-Rad® and other systems. Q-PAGE™ Midi (QP5XXX) Gels are suitable for Invitrogen® XCell SureLock® Mini-Cell, Invitrogen® Mini Gel Tank, Hoefer SE260, and other systems.

CE-IVDR marked in accordance with the European Commission Regulation (EU) No. 2017/746.
Ideal for use in in vitro diagnostic workflows
Simultaneous isolation of both host RNA and microbial RNA (universal protocol)
Isolate full diversity of RNA from large RNA down to small and microRNAs
Eliminates PCR inhibitors including humic acids
High quality RNA for sensitive downstream applications
This kit provides a convenient and rapid method to purify total RNA from small amounts of stool samples. All types of stool samples can be processed with this kit, including animal fecal samples, manure and samples collected using Norgen’s Stool Nucleic Acid Collection and Transport Devices Dx (Cat. Dx45660). The kit removes all traces of humic acids using rapid and simple spin column procedures. Bead tubes are also provided for effective homogenization of stool. The kit purifies all sizes of RNA, from large mRNA and ribosomal RNA down to microRNA and small interfering RNA. Both host and microbial RNA is recovered. The protocol does not rely on the use of phenol or chloroform, thereby providing a user friendly procedure and allowing high-throughput analysis. The purified RNA is of the highest integrity, and can be used in a number of downstream applications including real time PCR and reverse transcription PCR for gene expression analysis. The procedure can be completed in approximately 30 minutes.
NOTE: This product is not available for sale in the United States.
Storage Conditions and Product Stability All solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment.
