Figure 1. High Quality of Isolated RNA with Better Size Exclusion. Small RNA was isolated from HeLa cells using Norgen"s microRNA Purification Kit (Lanes C and D) and a competitor"s kit (Lanes A and B). Ten microliters of the 50 µL purified small RNA were run on an 8% urea-agarose gel. Lane M is Norgen"s 100b RNA ladder. Note that Norgen"s kit is isolating only the small (<200 nt) RNA species, with no contaminating larger RNA.

Figure 2. Efficient Removal of Large RNA Species. Different RNA species were isolated from 10
6 HeLa cells, resolved on an Agilent® Lab-On-A-Chip and electropherograms were generated. Panel A contains all the RNA species present in 10
6 HeLa cells as isolated with Norgen"s Total RNA Purification Kit, and acts as a control. Panel B and C contain RNA that was isolated from 10
6 HeLa cells using Norgens microRNA Purification Kit. One microliter of the 50 µL purified RNA for each fraction was loaded. Panel B shows the large RNA species removed using the Large RNA Removal Columns, and no small RNA can be detected. Panel C shows the small RNA that is isolated using the microRNA Enrichment Columns, and shows that there is no contamination of the small RNA with any large RNA species above 200 nt. This demonstrates the effective separation of the small RNA from the large RNA species using Norgen"s microRNA Purification Kit.

Figure 3. Effective Small RNA Amplification by End-Point RT-PCR. Norgen"s microRNA Purification Kit isolates small RNA that could be amplified in RT-PCR using the poly (A) polymerase extension method. Small RNA was isolated from 1 million HeLa cells, and10µLof the 20 µL isolated small RNA were polyadenylated in a 50 µL Poly-(A)-Polymerase reaction. Seven microliters of the polyadenylated RNA were used in a 20 µL reverse transcription reaction with a poly T adaptor primer. One microliter of the reverse transcription was used in a 20 µL PCR reaction with primers against the human microRNAs (miR-21) and 5S rRNA. Panel A shows the amplification of the miR-21 transcript from small RNAs while Panel B shows the 5S rRNA amplification from small RNAs. Lane 1 in both panels shows the results when total RNAisolated from 1 million HeLa cells using Norgen"s Total RNA Purification Kit was used as a control. Lanes 2 and 3 contain the successful RT-PCR when the microRNA isolated using Norgen"s microRNA Purification Kit was used as the template, and Lanes 4 contain the non-template control. The RT-PCR was successful for both reactions using the microRNA as the template. All PCR products were resolved on a 1X TAE, 3% agarose gel using Norgen"s PCR Ranger asthe molecular weight ladder.

Figure 4. Better Recovery of miRNAs by Norgen"s microRNA Purification Kit. Norgen"s microRNA Purification Kit recovers microRNA more effectively than its competitors. Small RNA was isolated from 0.75 million HeLa cells using Norgen"s microRNA Purification Kit and a competitors"kits. Relative expression of (A) miR-21, (B) miR-19 and (C) 5S rRNA was determined by RT-qPCR of polyadenylated total RNA samples. RT-qPCR was performed according to Shi and Chiang (2005). Fifteen microliters of the 50 µL isolated RNA were polyadenylated in a 50 µL Poly-(A)-Polymerase reaction. Four microliters of the polyadenylated RNA were used in a 20 µL reverse transcription reaction with a poly T adaptor primer. One microliter of the reverse transcription was then used in a 20 µL qPCR reaction with primers against the human microRNAs (miR-19 and miR-21) and house-keeping small RNA (5S rRNA). The resulting threshold cycle (Ct) values were summarized in the graph. Blue = Norgen"s microRNA Purification Kit; orange = Silica-basedCompetitor micro-RNA Kit; green = Silica-basedCompetitor Total RNA Kit; red = Phenol-based reagent protocol; yellow= No Template Control. Norgen"s microRNA Purification Kit recovered more miRNAs (lower Ct) than competitor"s microRNA-specific Kit.]">

microRNA Purification Kit
This kit provides a rapid method for the isolation and purification of small RNA molecules (< 200 nt) from cultured animal cells, small tissue samples, bacterial cells, plants and blood.
Two columns are provided with this kit. The first column captures large RNA, while the small RNA are captured on a second column and are eluted concentrated in 25 µL of nuclease-free water.
The small RNA can be used in various downstream applications relating to miRNA profiling, gene regulation and functional analysis. The eluted RNA is ready for RT-qPCR, microarrays, and NGS applications.
Background
These small RNAs include regulatory RNA molecules such as microRNA (miRNA) and short interfering RNA (siRNA), as well as tRNA and 5S rRNA. Small RNA molecules are often studied due to their ability to regulate gene expression. miRNAs and siRNAs are typically 20-25 nucleotides long, and regulate gene expression by binding to mRNA molecules and affecting their stability or translation.

Company Overview:
Norgen Biotek Corp. is an innovative, biotechnology company focusing principally on advancing novel, innovative sample preparation products for nucleic acid (DNA & RNA) and protein purification, clean-up and concentration. Norgen has one platform technology with many applications based on a proprietary resin that can be applied in the purification of DNA, RNA and proteins. The uniqueness and novelty of this technology has been recognized by the National Research Council through awarding Norgen the prestigious “Innovation Leader Award for 2003”. The company holds more than a dozen issued patents and several others are pending. Norgen currently manufactures over 40 products that are used by researchers working in genomics and proteomics in academia, pharma/biotech companies, and government institutions. These products are based on Norgen’s novel technology and include:
1. RNA purification kits : Norgen manufactures the leading products in the world for the purification of total RNA, microRNA, cy toplasmic and nuclear RNA, and RNA from the exfoliated cells found in urine. Norgen’s RNA kits are the only kits in the world that isolate true total RNA (including microRNA) without the use of phenol extraction steps. Simply stated, our kits are currently the Gold Standard in the RNA purification area, offering many significant competitive advantages. Due to the fact that Norgen’s RNA purification products do not involve phase separation based on the use of phenol, they can easily be adapted to isolate total RNA, including microRNA, in high throughput. In addition, Norgen is also pioneering kits for macromolecule fractionation using one column without sample splitting. Towards this goal, Norgen has developed the RNA/DNA/Protein Kit (3-in-1) for purification of all 3 macromolecules from one sample sequentially. In addition, a recent product has been developed that added microRNA fractionation to the RNA/DNA/Protein Kit, termed the All-in-One Purification Kit (4-in-1). These products are unique and novel and offer a substantial cost and time savings over sample splitting and a several-column approach. These powerful and novel tools are designed for researchers who are interested in studying the genome, proteome and transcriptome of a single sample, such as for studies of gene expression including gene silencing experiments or mRNA knock-downs and studies involving biomarker discovery.
2. ProteoSpin™ brand protein kits : For desalting, detergent and endotoxin removal, concentration, inclusion body screening, abundant serum protein depletion, urine protein concentration and on-column peptide preparation for mass spec analysis.
3. DNA kits: For plasmid isolation, PCR purification, gel extraction, eukaryotic and prokaryotic genomic DNA isolation, and front-end sample preparation for diagnostics and forensic applications (including milk bacterial DNA isolation, urine bacterial DNA isolation, saliva DNA isolation, and urine DNA isolation).
4. Molecular weight ladders : A broad range of DNA, RNA and protein ladders are available.
Company Location
Norgen is located in a new, 24,000 square foot state-of-the-art facility in the middle of Niagara region, Ontario, Canada one block from Brock University. We are only 30 minutes from Buffalo and 1 hour from Toron to. Also, Niagara Falls and the wineries of Niagara-on-the-Lake are located within 10 minutes of the facility. The building itself is on a large property adjacent to the 406 Highway in Thorold’s technology district, and the property offers much room for expansion.
