8x10ml PRP Centrifuge Rotor

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 

ExcelRT™ Reverse Transcription Kit is a complete, efficient and convenient kit to synthesize high quality first strand cDNA. This kit contains ExcelRT™ Reverse Transcriptase, which is able to synthesize the first strand cDNA at 37~50°C. The ExcelRT™ Reverse Transcriptase is a recombinant Moloney Murine Leukemia Virus (M-MLV) reverse transcriptase, which is designed to reduce RNase H activity and create better thermal stability. This kit also contains RNAok™ RNase Inhibitor, which is active against RNase A, RNase B, and RNase C. This product is supplied with oligo (dT)₂₀ and random hexamers, which are used to synthesize cDNA from poly(A) tailed mRNA and total RNA, respectively. 

Features

• Contains all components for reverse transcription 
• High yield 
• Thermostable, up to 50°C, during first strand synthesis 
• High processivity, generating cDNA up to 8 kb 
• Reduced RNase H ribonuclease activity 

Application

• Generation of first strand cDNA from total RNA or mRNA.
• Suitable for generating cDNA from RNA with strong secondary structure which can be reduced at temperature up to 50°C.

Storage

-20°C for 24 months 

High yield

High sensitivity

Thermostable, up to 50°C, during first strand synthesis
