Introduction

This product uses an improved salt precipitation purification method to provide a safe and economical solution for High Weight genomic DNA extraction from blood samples, tissue samples, cultured cells, oral swabs, bacteria, and other samples. The extraction does not require the use of toxic phenol chloroform or any expensive reagents, making it the most economical reagent kit for nucleic acid extraction at present. This kit has no limit on the amount of sample used and can flexibly adjust various amounts of samples. The obtained DNA can be directly used for experiments such as PCR, enzyme digestion, Southern hybridization, and the Third-generation sequencing.

Principles

SolPure DNA Kits is an improved salt precipitation purification method. (Blood samples are lysed in red blood cell lysis buffer to remove red blood cells, and white blood cells are collected by centrifugation.) After lysis, DNA is released into the lysis buffer. RNA is removed by RNASE A. High salt solution is added to precipitate proteins and impurities. Centrifuge to remove precipitate and obtain supernatant containing only DNA. Add isopropanol to precipitate and recover DNA. Wash with 70% ethanol to remove salt, and finally add Buffer TE to dissolve DNA.

Storage and Stability

RNase A and Proteinase K should be stored at 2–8°C upon arrival. However, short-term storage (up to 4 weeks) at room temperature (15–25°C) does not affect its performance. The remaining kit components can be stored dry at room temperature (15–25°C) and are stable for at least18 months under these conditions. The entire kit can be stored at 2–8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature when used.

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.
