GeneAb™ Tau

Overview

• No need to immediately process samples
• Nucleic acid preservation at room temperature over 2 years for DNA and up to 7 days for RNA
• Ship fecal samples at room temperature safely
• Compatible with most DNA/RNA isolation methods
• Optimized isolation procedure using Norgen’s Microbiome DNA Isolation Kit

Norgen’s Fecal Swab Collection and Preservation System is designed for collection, ambient storage and transport of nucleic acids from stool specimens. The Fecal Swab Collection and Preservation System tubes contain Norgen’s Stool Preservative in a liquid format. The user simply collects the specimen using the provided swab, and then transfers the swab into the Stool 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 upon arrival at the testing facilities until RNA purification.

Propargyl-PEG7-t-butyl ester comprises a propargyl group and a t-butyl protected carboxyl group. The propargyl group reacts with azide compounds via copper catalyzed Click Chemistry to form a stable triazole linkage. Under acidic conditions, the carboxyl group can be deprotected. The hydrophilic PEG units enhance solubility of the molecule in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
