Overview
Extract high quality & quantity total RNA including miRNA
No phenol step required – isolate all RNA in one fraction
Rapid processing in under 40 minutes
Isolate total RNA from a wide variety of specimens
Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix
Norgen’s Total RNA Purification Maxi Kit provides a rapid method for the isolation and purification of total RNA from cultured animal cells, tissue samples, blood, bacteria, yeast, fungi, plants, and viruses. The kit purifies all sizes of RNA, from large mRNA and ribosomal RNA down to microRNA (miRNA) and small interfering RNA (siRNA). The RNA is preferentially purified from other cellular components such as proteins, without the use of phenol or chloroform. The purified RNA is of the highest integrity, and 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.
Norgen’s Purification Technology
Purification is based on spin column chromatography using Norgen’s proprietary resin as the separation matrix. The RNA is preferentially purified from other cellular components such as proteins without the use of phenol or chloroform. The process involves first lysing the cells or tissue of interest with the provided Buffer RL (please see the flow chart on page 4). Ethanol is then added to the lysate, and the solution is loaded onto a maxi spin column. Norgen’s resin binds RNA in a manner that depends on ionic concentrations. Thus only the RNA will bind to the column, while the contaminating proteins will be removed in the flowthrough or retained on the top of the resin. The bound RNA is then washed with the provided Wash Solution A in order to remove any remaining impurities, and the purified total RNA is eluted with the Elution Solution A. The purified RNA is of the highest integrity, and can be used in a number of downstream applications.

The NGS Library Circularization Kit (MGI Platform) was developed for preparation of single-stranded circular DNA libraries for next generation sequencing (MGI platform).
The kit uses linear dsDNA libraries (MGI platform) as input and enriches the circularized single-stranded DNA libraries. The circularization kit has a higher library circularization efficiency (25%) as compared to other vendors (7-15%).
