Introduction
The HiPure Minipreps system provides a fast, simple, and cost-effective plasmid DNA miniprep method for routine molecular biology laboratory applications. HiPure Miniprep Kits use silica membrane technology to eliminate the cumbersome steps associated with loose resins or slurries. Plasmid DNA purified with Mini Kits is immediately ready for use. Phenol extraction and ethanol precipitation are not required, and high quality plasmid DNA is eluted in a small volume of Tris buffer or water.

Principle
The HiPure Plasmid procedure is based on alkaline lysis of bacterial cells followed by adsorption of DNA onto silica in the presence of high salt. The unique silica membrane used in the kit completely replaces glass or silica slurries for plasmid DNA minipreps. The procedure consists of 3 basic steps: Preparation and clearing of a bacterial lysate by alkaline method，then transfer the supernatant to column to bind DNA. After washing proteins and other impurities, nucleic acid was finally eluted with low-salt buffer (10mm Tris, pH9.0, 0.5mm EDTA).
Advantages
1. High throughput: processing 96 samples at once; 2. High yield: The purified plasmid yield can reach up to 30μg, which is greater than the yield of the magnetic bead method kit; 3. Detoxification: endotoxin content <0.1EU/μg; 4. Fast: The entire extraction can be completed in 60 minutes without the need for time-consuming alcohol precipitation;

Storage and Stability
The kit components can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions. If any precipitates form in the buffers, warm at 37℃ to dissolve. After addition of RNase A，Buffer P1 is stable for 6 months when stored at 2-8°C.

Overview
Purification and enrichment of intact cell culture media exosomes for functional studies
Isolate all sizes of RNA, including microRNA, irrespective of size or GC content, without bias.
Versatile cell culture media input volumes
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 spin column chromatography that uses Norgen’s proprietary resin
The purified RNA is suitable for a variety of downstream applications, including Small RNA Sequencing. Find out more information on Norgen’s NGS services
Norgen’s Cell Culture Media Exosome Purification and RNA Isolation Kits constitute an all-in-one system for the purification of exosomes and the subsequent isolation of exosomal RNA from different cell culture media sample volumes. The purification is based on spin column chromatography that employs Norgen’s proprietary resin. The kit is designed to isolate all sizes of RNA, including microRNA, irrespective of size or GC content, without bias. These kits provide a clear advantage over other available kits in that they do not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or protease treatments. Moreover, the kits allow the user to elute into a flexible elution volume ranging from 50 µL to 100 µL. The RNA isolated from the purified exosomes 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, reverse transcription PCR, Northern blotting, RNase protection and primer extension, and expression array assays.
