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.

Norgen’s 2X One-Step RT-PCR Master Mix is a ready-to-use solution that contains components required for RT-PCR amplification of RNA templates. The mix includes M-MuLV reverse transcriptase, Taq DNA polymerase, dNTPs, reaction buffer, MgCl2, KCl, and a PCR enhancer/stabilizer. The user needs only to add the template, the primer set and water to the Master Mix to set up the RT-PCR reaction. This convenient 2X One-Step RT-PCR Master Mix reduces the time required to set up PCR reactions and reduces the possibility of contamination, particularly when preparing large numbers of reactions. The optimized master mix allows for robust amplification of RNA templates with high yields of PCR products.
Taq DNA Polymerase is a highly thermostable DNA polymerase that possesses a 5´→ 3´ polymerase activity and a very low 5´→ 3´ exonuclease activity. The source of Taq included with Norgen’s 2X One-Step RT-PCR Master Mix is an E. coli strain with a cloned Taq DNA Polymerase gene from Thermus aquaticus YT-1. M-MuLV Reverse Transcriptase is an RNA-directed DNA polymerase that can synthesize a complementary DNA strand initiating from a primer using either RNA (cDNA synthesis) or single-stranded DNA as a template. The source of the Reverse Transcriptase included with Norgen’s 2X One-Step RT-PCR Master Mix is an E. coli strain with a cloned reverse transcriptase gene from M-MuLV.
Norgen’s 2X One-Step RT-PCR Master Mix is available in 3 convenient sizes:
Cat # 28113 – 100 reactions (sufficient for 100 reactions x 20 µL reaction volume)
Cat # 28114 – 200 reactions (sufficient for 200 reactions x 20 µL reaction volume)
Cat # 28115 – 500 reactions (sufficient for 500 reactions x 20 µL reaction volume)
