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.

Description

FluoroVue™ Nucleic Acid Gel Stain (10,000X) is specially designed for in-gel use and is a safer replacement for conventional Ethidium bromide (EtBr), which poses a significant health and safety hazard to its users. It is a fluorescent stain which offers highly sensitive detection of double-stranded or single-stranded DNA and RNA in a convenient manner. FluoroVue™ Nucleic Acid Gel Stain offers high sensitivity that is several times greater than EtBr. 

FluoroVue™ Nucleic Acid Gel Stain is compatible with both conventional UV gel-illumination systems as well as harmless long wavelength blue light illumination systems, like B-BOX™. When bound to nucleic acids, FluoroVue™ Nucleic Acid Gel Stain has a fluorescent excitation maximum of 250 and 482 nm, and an emission maximum of 509 nm. Therefore, it can replace EtBr without the need of changing existing lab imaging systems.

Features:

• Excellent for in-gel staining
• Sensitivity: 0.14 ng (DNA) or 1 ng (total RNA)
• A safer alternative to EtBr
• Compatibility: suitable to blue or UV light
• Increased cloning efficiency (blue light)

Storage

Protected from light
4°C for 12 months
-20°C for 24 months
