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.

Introduction

The HiPure Liquid RNA & miRNA Kit integrates phenol/guanidine-based sample lysis and silica membrane purification of total RNA. MagZol LS Reagent, included in the kits, is a monophasic solution of phenol and guanidine thiocyanate designed to facilitate lysis of liquid sample and inhibit RNase. The high lysis efficiency of the reagent and the subsequent removal of contaminants by organic phase extraction enable the use of up to 0.25ml liquid sample per mini spin column.

Specifications

Principle

0.25ml liquid samples are homogenized in 0.75ml MagZol LS Reagent. After addition of chloroform, the homogenate is separated into aqueous and organic phases by centrifugation. The upper, aqueous phase is extracted, and ethanol is added to provide appropriate binding conditions. The sample is then applied to the spin column, where the total RNA (up to 100 µg) binds to the membrane and phenol and other contaminants are efficiently washed away. High-quality RNA is then eluted in 30–100µl of RNase-free water.

Advantages

• High quality – high purity total RNA can be directly used in various sensitive downstream applications
• Fast – isolation of several samples can be completed in 40 minutes by using column purification method
• Safety – no phenol chloroform extraction required
• Sensitive – direct lysis of blood, plasma and other samples without separation of leukocytes

Storage and Stability

MagZol LS Reagent should be stored at 2-8°C upon arrival. However, short-term storage (up to 24 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions.
