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).

Fentanyl (FYL) Detection Kit (Rapid Lab) is a lateral flow chromatographic immunoassay for the qualitative detection of Fentanyl/Norfentanyl in liquid and powder substances at the cut-off concentration of 200 ng/mL.
It is specific for Fentanyl screening with no significant cross reactivity to other opiates, such as Morphine and Heroin.
Interpretation of test results are: positive (one line), negative (two lines), invalid (no lines or no control line).
For professional institutions use only, not for self-testing.

Sample type purification kit guide
The 16S V1-V3 Library Preparation Kit for Illumina consists of the reagents and components required for library preparation of the 16S V1-V3 amplicon libraries to be used for next-generation sequencing on Illumina platforms. All molecular reagents including primers, enzyme mixes, indexes, and buffers are provided. Instructions for PCR clean up with the AMPure XP Magnetic Beads (supplied by customer) are also included for rapid purification of nucleic acid products generated at two steps of the workflow. The library prep workflow could be used for purified DNA inputs from different sources including stool, soil, water, saliva, plant, urine, skin swab, vaginal swab, cheek swab, nasal swab, plasma/serum, tongue swab, gum swab, and others.
The 16S V1-V3 Library Preparation Kit for Illumina has a streamlined procedure that reduces the handling time such that the library prep procedure can be completed in approximately 4 hours (see diagram below). Input DNA is first subjected to targeted PCR to amplify the V1-V3 region of the DNA encoding 16S rRNA. The post-PCR reaction is then cleaned up using AMPure XP beads. Dual index primers are then added using a limited-cycle PCR. The indexed amplicons flanked by 5′ and 3′ barcoded adaptors are then cleaned using AMPure XP beads. The libraries are then ready for quantification, pooling and sequencing.

Storage Conditions and Product Stability
Norgen’s 16S V1-V3 Library Prep Kit for Illumina is shipped as one kit box (for the 24 prep kit) or two sub-component kits (for the 96 prep kit). All kits should be stored at -20°C upon arrival.
All kit components should remain stable for at least 1 year when stored at the specified storage conditions.
