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.

Introduction

HiPure Bacterial RNA Kit uses silica gel column purification to simplify the extraction. The whole process does not require phenol chloroform extraction and time-consuming alcohol precipitation. The kit is suitable for efficiently extracting RNA from various bacterial samples. The purified RNA can be directly used for RT-PCR, Northern hybridization, etc. The kit has included lysozyme and glass beads, which can be used to treat gram-negative bacteria which is easy to be lysed, as well as gram-positive bacteria which is hard to be lysed, including enterococcus faecalis, staphylococcus, etc.

Principle

Hipure silica gel column is based on glass fiber filter membrane with high binding force. Under the condition of high concentration of ionizing agent (such as guanidine hydrochloride or guanidine isothiocyanate), the filter membrane can adsorb nucleic acid through hydrogen bond and electrostatic, while protein and other impurities are not adsorbed and removed. The filter membrane adsorbed with nucleic acid is washed to remove the residual protein and salt. Finally, the nucleic acid adsorbed on the filter membrane can be washed out with low salt buffer (such as buffer TE) or water. The obtained nucleic acid has high purity and can be directly used in various downstream experiments.

Advantages

• Fast – several samples can be extracted in 30 minutes
• High purity – the purified RNA can be directly used in various downstream applications
• High recovery – RNA can be recovered at the level of PG
• Good repeatability – silica gel column purification technology can obtain ideal results every time
• Broad spectrum – it can deal with various bacteria, including Gram-positive bacteria that are difficult to be lysed
• Sufficient components – the kit contains carried lysozyme and glass beads

Storage and Stability

The kit components can be stored at room temperature (15–25°C) and are stable for at least 18 months under these conditions. Due to the lack of antibacterial agents, RNase Free Water may be contaminated by bacterial or fungal when placed or operated at room temperature. It is recommended to pack and store at 2-8°C to reduce contamination.
