Principle

Biological samples are first lysed and homogenized in a highly denaturing guanidine isothiocyanate-containing buffer, which immediately inactivates DNases and RNases to ensure isolation of intact DNA and RNA. The lysate is then passed through a Mini spin column. This column, in combination with the high-salt buffer, allows selective and efficient binding of genomic DNA. Flow-through from the column is digested by Proteinase K in the presence of ethanol. This optimized digestion, together with the subsequent addition of further ethanol, allows appropriate binding of total RNA, including miRNA, to the column. Contaminants are efficiently washed away and high-quality RNA is eluted.

Advantages

• High quality – one step RNA extraction reagent combined with silica gel column can obtain the highest concentration
• Fast – several samples can be extracted in 40 minutes
• High applicability – samples including animals, plants, bacteria, cells, etc.
• High concentration – efficiently remove macromolecular RNA, enrich small RNA and improve sensitivity
• Safe – no phenol chloroform extraction and no use of Trizol reagent

Storage and Stability

Proteinase K should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions.

The Kit is designed for purification of total RNA, including miRNA and other small RNA molecules (18nt), from cultured cells and various animal and human tissues, including difficult-to-lyse tissues samples.

OverView

AZscript™ Reverse Transcriptase (RT) is an RNA-dependent DNA polymerase used to synthesize complementary DNA (cDNA) from an RNA template.

While originating from Moloney Murine Leukemia Virus (M-MLV), AZscript RT has been engineered for increased thermostability and reduced RNase H activity.

In cDNA synthesis a higher reaction temperature can reduce RNA secondary structures and improve efficiency and specificity of the reaction.

Furthermore, a reduction in RNase H activity increases performance of the cDNA synthesis, especially for longer transcripts.

The combination of these tailored features ensures that AZscript Reverse Transcriptase provides an effective and reliable solution for various cDNA synthesis applications.

Key Features 

• Increased thermostability.
• Reduced RNase H activity.

Applications

• cDNA synthesis
• Demonstrated performance in RT-qPCR

Overview

• Ensure optimal results for sensitive applications like NGS
• Up to a tenfold increase in microRNA mapping during sequencing runs to reduce costs
• Purification and enrichment of intact cell culture media exosomes for functional studies
• No phenol extractions, Proteinase K treatment, nor carrier RNA required
• No time-consuming ultracentrifugation, filtration nor special syringes required
• No precipitation reagents nor overnight incubation required
• Pure exosomes are purified and are free-from any other RNA-binding proteins
• Purification is based on EXTRAClean spin column chromatography that uses Norgen’s proprietary resin separation matrix

Norgen’s EXTRAClean Cell Culture Media Exosome Purification and RNA Isolation Kits constitute all-in-one systems for the purification of exosomes and the subsequent isolation of RNA from different cell culture media sample volumes. The purification is based on spin column chromatography that employs Norgen’s proprietary resin. The EXTRAClean columns undergo stringent processing and rigorous quality control measures to minimize contamination traces, ensuring optimal results for sensitive applications such as NGS. The kit is designed to isolate all sizes of RNA, including microRNA. The kit provides a clear advantage over other available kits in that it does not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or protease treatments. Moreover, the kits allows the user to elute into flexible elution volumes ranging from 50 μL to 100 μL. The purified RNA is free from any protein-bound circulating RNA and is of the highest integrity. The purified RNA can be used in a number of downstream applications including real time PCR, Sequencing based applications, reverse transcription PCR, Northern blotting, RNase protection and primer extension, and expression array assays.
