DBCO-PEG24-acid

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.

Description 

AccuBand™ 100 bp DNA marker II is composed of 6 individual DNA fragments, presenting 2k, 1k, 750, 500, 250 and 100 bp sharp bands respectively. This product contains 1 enhanced band (750 bp) for easy identification of bands. AccuBand™ 100 bp DNA marker II is ready-to-use, containing loading buffer with tracking dyes of dual colors (orange and cyan). To improve the faint visibility of low molecular weight bands frequently occurred in use of conventional DNA markers, AccuBand™ 100 bp DNA marker II provides sufficient amount of DNA for 250 and 100 bp fragments, and thus ensuring clear observation of all DNA bands ranging from 100 bp to 2k bp, either in agarose gel or in polyacrylamide gel electrophoresis. 

Features

• Sharp bands
• Suitable for polyacrylamide gel electrophoresis
• Quick reference— enhanced bands 
• Ready-to-use— premixed with loading dye for direct loading
• Stable— room temperature storage over 6 months
