Description

Formaldehyde is an organic compound with the formula CH2O. It is mainly used in the production of industrial resins but has been found to be used as a preservative, disinfectant and biocide. Because of its toxicity and volatility formaldehyde poses a significant risk to human health. Attogene test uses the property of formaldehyde to react with the Formaldehyde Reaction Powder (FRP) to form a purple-red tetrazine. The formaldehyde concentration is measured by visual comparison of the reaction with the color scale derived from the Color Card.

Where formaldehyde is found

Formaldehyde is found in:

• Resins used in the manufacture of composite wood products (i.e., hardwood plywood, particleboard and medium-density fiberboard)
• Building materials and insulation
• Household products such as glues, permanent press fabrics, paints and coatings, lacquers and finishes, and paper products
• Preservatives used in some medicines, cosmetics and other consumer products such as dishwashing liquids and fabric softeners
• Fertilizers and pesticides

It is a byproduct of combustion and certain other natural processes, and so is also found in:

• Emissions from un-vented, fuel burning appliances, like gas stoves or kerosene space heaters.
• Cigarette smoke.

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

The ExcelTaq™ Hot Start II DNA Polymerase is a mixture of an aptamer-based inhibitor and a recombinant thermo-stable Taq DNA polymerase designed for preventing or minimizing non-specific DNA amplification in PCR reaction. The inactivation of polymerase is achieved by a reversible binding of the aptamer to the polymerase at temperatures below 45°C. The aptamer inhibitor releases polymerase during normal PCR cycling. The aptamer-based inhibition omits the time-consuming initial activation step required by chemically modified or antibody-based hot start polymerases.

The high specificity and sensitivity of ExcelTaq™ Hot Start II DNA Polymerase allows sensitive detection from limited amount of DNA templates, such as 1 pg of cDNA or 1 fg of plasmid DNA. With a high DNA synthesis rate and high thermo-stability, the ExcelTaq™ Hot Start II DNA Polymerase allows reactions to be set up at room temperature and is suitable for common and specialized PCR applications

Features

• Aptamer-based hot start PCR
• Reversible enzyme inactivation
• Omits extra enzyme activation step
• Convenient for room temperature PCR set-up
• High yield and specificity of target amplicons
• Wide range of amplicon length (up to 10 kb)
• High sensitivity (as low as 1 fg of plasmid)

Applications 

• High specificity PCR
• Generation of PCR products for TA cloning
• Routine PCR, multiplex PCR, colony PCR, and RT-PCR

Storage

-20°C for 24 months
