Overview

• The preservative provides sample homogeneity eliminating sample variability
• Preserve and transport DNA & RNA safely at ambient temperature
• Nucleic acid preservation at room temperature over 2 years for DNA and 7 days for RNA
• No cold shipping/storage needed – hassle-free and cost effective
• Isolate nucleic acids for any application including 16s NGS
• Robust preservation over a range of temperatures
• Customizable with various accessories for easy and safe collection
• Eliminates odor and renders samples safe and non-infectious

Norgen’s Stool Nucleic Acid Collection and Preservation Tubes are designed for the rapid preservation of nucleic acids from fresh stool specimens. The Stool Nucleic Acid Collection and Preservation Tubes contain Norgen’s Stool Preservative in a liquid format. The user simply collects stool into the tubes (fill up to the line indicated on the tube) and mixes gently until the stool is well submerged under the preservative. The Stool 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 Stool 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 Stool Preservative allow samples to be stored at room temperature for over 2 years for DNA and 7 days for RNA. To extend the stool RNA stability in the preservative, storage at -20°C or -70°C is recommended at the arrival to testing facilities until the RNA purification.

Introduction

Usages:

For differentiation of enterobacteriaceae.

Principle:

Peptone, beef extract powder and yeast extract powder provide nitrogen, vitamins, minerals; lactose, dextrose into fermentable sugars, which produce acid when measured by the phenol red indicator, acid yellow, basic red; thiosulfate sodium can be reduced to some bacteria to hydrogen sulfide, to produce a black iron sulfide and iron salts; sodium chloride to maintain osmotic equilibrium; agar as medium coagulant.

Formulation(per liter):

Peptone 20g

Beef extract powder 3g

Yeast extract powder 3g

Lactose 10g

Dextrose 1g

Sodium chloride 5g

Ferric ammonium citrate 0.5g

Sodium thiosulfate 0.5g

Agar 12g

Phenol red 0.05g

Final pH 7.4 ± 0.2

How to use:

1.Suspend 54.5g in 1L of distilled water , stirring heated to boiling ,autoclave at 121 for 15 minutes.
