Norgen’s TaqMan 2x PCR Master Mix is a ready-to-use TaqMan 2x PCR Master Mix solution that contains a PCR internal control which can be detected by HEX/VIC channel in a real-time PCR machine. By detecting the internal control users can validate the DNA template quality, thereby preventing any false negatives in the PCR results. The user needs only to add template, target TaqMan primer/probe mix and water to set up the TaqMan real-time PCR.
PCR Control: TaqMan 2x PCR Master Mix contains PCR control primers/probe (HEX/VIC) and PCR control template. The PCR control reaction in the TaqMan 2x PCR Master Mix is optimized to not interfere with target amplification. The fluorescence of the target probe should not be HEX/VIC.

Reagents Supplied – Cat # 28341
TaqMan 2x RT-PCR Master Mix (3 Vials, 100 Reactions) – Sufficient reagent for 100 x 20 µL reactions
Storage Conditions and Product Stability Norgen’s TaqMan 2x PCR and 2x RT-PCR Master Mixes should be stored at -20ºC. For everyday use an aliquot can be stored at 4ºC for up to three months. The Master Mix is stable for multiple freeze-thaw cycles. When stored at the proper temperature this reagent is stable for at least 1 year.
The 16S V3-V4 Library Preparation Kit for Illumina consists of the reagents and components required for library preparation of the 16S V3-V4 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 V3-V4 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 V3-V4 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 V3-V4 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.
These kits provide a fast, reliable and convenient spin column method for the isolation of high quality, high purity and inhibitor-free cell-free circulating DNA (cfc-DNA) from plasma/serum sample. These kits are designed to isolate all sizes of cfc-DNA from either fresh or frozen plasma/serum samples and the purified DNA is eluted into a flexible elution volume ranging from 25 µL to 50 µL. The purified plasma/serum cfc-DNA is fully compatible with all downstream applications including PCR, qPCR, methylation-sensitive PCR and Southern Blot analysis, microarrays and NGS.
Background
Plasma/Serum cell-free circulating DNA (cfc-DNA) has the potential to provide biomarkers for certain cancers and disease states as well as fetal DNA in maternal blood. Currently, significant advancements are being made in utilizing cfc-DNA as biomarkers for the early diagnosis, prognosis and monitoring of therapy for several cancer types and autoimmune diseases. Cell-free mitocondrial DNA (cfmtDNA) is also under investigation for its clinical significance. This cfc-DNA is usually present as short fragments of less than 1000 bp. In addition, cell-free fetal DNA has been widely used as a non-invasive method for prenatal diagnosis including early identification of fetal sex, genetic studies for families at high risk for inherited genetic disorders, screening for Rhesus factor, screening for aneuploidy and identification of preeclampsia.

Storage Conditions and Product Stability All buffers should be kept tightly sealed and stored at room temperature (15-25°C) for up to 2 years without showing any reduction in performance. Norgen’s Plasma/Serum Cell-Free Circulating DNA Purification Kits contain ready-to-use Proteinase K solution, which is dissolved in a specially prepared storage buffer. The Proteinase K is stable for up to 2.5 years after delivery when stored at room temperature. To prolong the lifetime of Proteinase K, storage at 2–8°C is recommended.
