Overview

• CE-IVDR marked in accordance with the European Commission Regulation (EU) No. 2017/746.
• Ideal for use in in vitro diagnostic workflows
• No need to immediately process samples
• Total DNA, including viral DNA, preserved at room temperature over 4 months
• Total RNA, including viral RNA, preserved at room temperature over 2 months
• Inactivate microorganisms including bacteria, fungi, yeast and viruses
• Inactivates SARS-CoV-2 virus – Explore the Application Note
• Ship swab samples at room temperature safely
• Compatible with most DNA and RNA isolation methods

Norgen’s Total Nucleic Acid Preservation Tubes Dx are designed for ambient preservation and transport of total nucleic acids (DNA and RNA) from samples collected using a swab. The Total Nucleic Acid Preservation Tubes contain Norgen’s Total Nucleic Acid Preservative in a liquid format. The user simply collects the specimen using a sterile nylon flocked swab (not provided), and then transfers the swab into the Total Nucleic Acid Preservative. The Preservative prevents the growth of Gram-negative and Gram- positive bacteria and fungi, and also inactivates viruses allowing the resulting non-infectious samples to be handled and shipped safely. In addition, the Total Nucleic Acid Preservative eliminates the need to immediately process or freeze samples and allows the samples to be shipped to centralized testing facilities at ambient temperatures. The components of the preservative allow DNA samples to be stored at room temperature for over 4 months and RNA samples to be stored at room temperature for over 2 months. This kit is ideal for collecting and preserving nasal and oral swab samples for in vitro diagnostic use for medical purposes. This kit can be used to preserve viral RNA, including SARs-CoV-2 RNA for detection of COVID-19.

Norgen’s Total Nucleic Acid Preservation Tubes Dx are intended for use by professional users such as technicians, physicians and biologists experienced and trained in molecular biological techniques.

Norgen’s Total Nucleic Acid Preservation Tubes Dx do not provide a diagnostic result. It is the sole responsibility of the user to use and validate these devices in conjunction with a downstream in vitro diagnostic assay.

Shelf Life and HandlingThe tubes should be kept tightly sealed and stored at room temperature for up to 1 year without any reduction in performance (The collection due date is written on the device label and the kit box label).Once collected, RNA is stable for up to 2 months and DNA is stable for up to 4 months when the tubes are kept tightly sealed and stored at room temperature.

Overview

• CE-IVDR marked in accordance with the European Commission Regulation (EU) No. 2017/746.
• Ideal for use in in vitro diagnostic workflows
• Simultaneous isolation of both host DNA and microbial DNA  (universal protocol)
• Eliminates PCR inhibitors including humic acids
• Fully compatible with Norgen’s Stool Nucleic Acid Collection and Transport Tubes
• High quality DNA for sensitive downstream applications including PCR, qPCR, sequencing and microarray​

This kit provides a convenient and rapid method to isolate total DNA from fresh, frozen and preserved stool samples, including those preserved using Norgen’s Stool Nucleic Acid Collection and Preservation Devices Dx (Cat. Dx45660). The universal protocol conveniently allows for the isolation of total genomic DNA from all the various microorganisms and host cells found in the stool sample simultaneously. The kit removes all traces of humic acids and other inhibitors using Bead Tubes and a combination of chemical and physical homogenization and lysis, without the need of any phenol-chloroform extractions. A simple and rapid spin column procedure is then used to further purify the DNA with high yields and molecular weights of up to 50 kb plus.  The purified DNA is of the highest quality and is fully compatible with all downstream applications such as PCR, qPCR, NGS and microarrays since all humic acid substances and other PCR inhibitors are removed during the isolation process.

NOTE: This product is not available for sale in the United States.

Storage Conditions and Product Stability
All solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment.

PEG3-bis(Amino-Tri-(Propargyl-PEG2-ethoxymethyl)-methane) is a crosslinker consisting of six propargyl groups. The propargyl groups can form triazole linkage with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

SKU: 700004257

110 mL of prepared reagent (e.g. 500 assays of 0.22 mL)

The Acetic Acid GK format test kit is for use with auto-analysers and is suitable for the specific measurement and analysis of acetic acid (acetate) especially in wines, fruit juices, beverages and food products.

As part of Megazyme’s overall commitment to providing the highest quality products, we have developed this acetic acid kit that provides a specific and rapid assay for use with auto-analysers. The kit assay is based on the conversion of NAD⁺ to NADH and therefore provides a positive reaction (increase in absorbance) which offers a more robust assay.

The reagents, as supplied, are stable for a minimum of 2 years and the prepared reagents are stable for a minimum of 1 week (on-board stability). In addition, the prepared reagents can be stored frozen for longer term stability (see K-ACETGK Booklet for more details).

Advantages

• Excellent reagent stability 
• > 7 days at 4^oC or > 2 years below -10^oC when prepared for auto-analyser applications 
• > 2 years as supplied 
• Very rapid reaction (~ 5 min at 37^oC) 
• Linear calibration (R² ~ 0.997 up to 1.8 g/L sample)
