DBCO-PEG8-acid is an analog of DBCO-Acid with hydrophilic PEG linker and a DBCO group. The DBCO groups is commonly used for Click Chemistry reactions. The hydrophilic PEG chain allows for increased water solubility of compounds in aqueous media. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Overview
Collect from nasal, buccal, saliva, fecal, skin, surfaces, and more
Completely stabilize microbiota profiles from the point-of-collection
Minimize bias in data analysis: NGS (Metagenomics/Microbiome), PCR and microarrays
No need to immediately process samples: ship and store at ambient temperatures
DNA preservation at room temperature over 2 years
Renders sample non-infectious for safe and easy shipping
Compatible with DNA isolation kits and protocols: Optimized isolation procedure using Norgen’s Microbiome DNA Isolation Kit
Norgen’s Swab Collection and DNA Preservation System is designed for collection, ambient storage and transport of DNA from samples collected using a swab, including nasal, buccal, saliva, fecal, skin, surfaces, etc. The Swab Collection and DNA Preservation System contains Norgen’s Swab Preservative in a liquid format. The user simply collects the specimen using the provided swab, and then transfers the swab into the Swab Preservative. The Swab 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 Swab 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 Swab Preservative allow DNA samples to be stored at room temperature for over 2 years.
DNA Isolation from Preservative
Swab samples collected and preserved using Norgen’s Swab Collection and DNA Preservation System are compatible with most DNA isolation methods. Samples stored in the tubes have been used successfully with most of Norgen Biotek’s DNA isolation kits and reagents. An optimized isolation procedure is available as part of Norgen’s Microbiome DNA Isolation Kit (Cat. 64100).
When stored at room temperature, unused Norgen Swab Preservative Tubes are stable through to the collect-before date without any reduction in performance. Please see the device insert or tube label for collect-before date.
CE-IVDR marked in accordance with the European Commission Regulation (EU) No. 2017/746.

Norgen’s Saliva DNA Collection and Preservation Devices are designed for 1) simple and non-invasive saliva collection and 2) preservation of DNA in saliva samples at ambient temperature. Each of the 50 Saliva DNA Collection and Preservation Devices consists of 3 components: (1) Saliva Collection Funnel and Collection Tube, (2) Collection Tube Cap, and (3) Norgen’s Saliva DNA Preservative contained within a sealed squeezable ampoule. Saliva samples are collected by spitting inside the Collection Funnel which has been assembled with the Collection Tube. After collecting the required volume of saliva the Collection Funnel is removed and the contents of the Preservative Ampoule are then added and mixed with the collected saliva. The Saliva Collection Tube is subsequently sent to the laboratory for DNA isolation and analysis. DNA can be isolated from the preserved saliva samples using Norgen’s Saliva DNA Isolation Kit (Cat# Dx45400). Each of Norgen’s Collection Tubes is labeled with a unique serial number that can be used for secure and anonymous tracking of the sample. The saliva DNA in preserved samples is stable for more than 2 years at room temperature. This kit is ideal for collecting and preserving DNA samples for in vitro diagnostic use for medical purposes.
Saliva DNA Preservative
Norgen’s Saliva DNA Preservative is an aqueous storage buffer designed for rapid cellular lysis and subsequent preservation of DNA from fresh specimens. The buffer 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 buffer eliminates the need to immediately process or freeze samples and allows the samples to be shipped to centralized testing facilities at ambient temperature. The components of the buffer allow samples to be stored for more than 2 years without any detectable DNA degradation.
DNA Isolation from Preservative
Prior to saliva DNA isolation, vortex the Collection Tube containing preserved saliva for 10 seconds and incubate at 55°C for one hour. Saliva DNA can now be isolated from the preserved saliva samples using Norgen’s spin-column based Saliva DNA Isolation Kit Dx (Cat# Dx45400) or other commercially available methods that have been validated for use with Norgen’s Saliva DNA Collection and Preservation Devices.
NOTE: This product is not available for sale in the United States.
The Collection Device should be kept tightly sealed and stored at room temperature for up to 3 years without any reduction in kit performance (The collection due date is written on the device label).
Once collected, saliva is stable for more than 2 years when kept tightly sealed and stored at room temperature.
The Collection Tube, the Collection Funnel and the Device Container of each Individual Saliva DNA Collection and Preservation Device are recyclable.
