The ExcelTaq™ 2X Q-PCR Master Mix (SYBR, no ROX) is a ready-to-use reagent with all the essential components for quantitative real-time PCR (qPCR) except primers and template. The master mix features high sensitivity and signal intensity as well as low background and better compatibility with cDNA templates derived directly from reverse transcription reaction mixture. The ExcelTaq™ 2X Q-PCR Master Mix (SYBR, no ROX) contains hot-start Taq polymerase in an optimized buffer with dsDNA specific SYBR green fluorescent dye. This master mix allows for sensitive, precise amplification, real-time tracking of the amplification process, and simultaneous quantification for targeted DNA molecules. With inert smart blue contrast dye, the ExcelTaq™ 2X Q-PCR Master Mix (SYBR, no ROX) is ready-to-use and greatly reduces pipetting errors, while largely improving the reproducibility of the process. The ExcelTaq™ 2X Q-PCR Master Mix is also compatible with a ROX reference dye if recommended by the manufacturer of the qPCR system.
Features
High sensitivity and signal intensity
Smart blue contrast dye as a visual aid for reaction setup
Better compatibility for reverse transcription
Low background
Storage
Protected from light. Aliquot to avoid multiple freeze-thaw cycles. -20°C for 12 months

Overview
CE-IVDR marked in accordance with the European Commission Regulation (EU) No. 2017/746.
Ideal for use in in vitro workflows
No need to immediately process samples
Nucleic acid preservation at room temperature over 2 years for DNA and 7 days for RNA
Ship stool samples at room temperature safely
Compatible with most DNA/RNA isolation methods
Norgen’s Stool Nucleic Acid Collection and Preservation Devices Dx are designed for the collection and preservation of nucleic acids from fresh stool specimens. The Stool Nucleic Acid Collection and Preservation Devices Dx – 50 contains 50 individual Stool Nucleic Acid Collection and Preservation Devices Dx. Each Stool Nucleic Acid Collection and Preservation Device Dx consists of Norgen’s Stool Nucleic Acid Collection and Preservation Tube Dx containing Norgen’s Stool Preservative in a liquid format. The user simply collects stool into the tubes (fill up to the line indicated on the tube) and mixes gently until the stool is well submerged under the preservative. The Stool Nucleic Acid Collection and Preservation Tube Dx is subsequently sent to the laboratory for DNA and/or RNA isolation and analysis. The stool DNA in preserved samples is stable for more than 2 years at room temperature, and the stool RNA in preserved samples is stable for 7 days at room temperature. DNA can be isolated from the preserved stool samples using Norgen’s Stool DNA Isolation Kit Dx (Cat. Dx27600) and RNA can be isolated from the preserved stool samples using Norgen’s Stool Total RNA Purification Kit Dx (Cat. Dx49500). These tubes are ideal for collecting and preserving DNA and RNA samples for in vitro diagnostic use for medical purposes.

Magen’s HiPure columns are prepared by high quality glass fiber filter membrane as raw materials through membrane cutting, membrane release, ring release, ring pressing, gland, weighing and other processes. HiPure nucleic acid adsorption columns have the characteristics of long-term stability and high binding capacity. Experiments show that the highest binding capacity and binding efficiency of HiPure nucleic acid adsorption columns are basically unchanged when stored at room temperature for 4 years.
The series of nucleic acid columns produced by Magen Biotech are based on carefully selected imported glass fiber membranes (GF/B, GF/D, GF/F). Columns production processes such as polypropylene injection molding materials, injection molding process, and downstream membrane packing and compression rings are strictly controlled. This is to ensure that the column has extremely high adsorption capacity and long-term stability. Compared with conventional products on the market, Magen’s columns are with varieties, and binding rate will not change when stored at room temperature for 4 years.

Adsorption Mechanism
Based on the negatively charged DNA skeleton, it has a high affinity for positively charged glass fibers. In high salt and ethanol solutions, DNA/RNA binds to glass fiber and interacts with hydrophilic matrix on silica through hydrogen bond. DNA/RNA is tightly bound. All pollutants can be removed by washing solution. At high salt concentration, nucleic acids selectively bind to silica gel membrane, while other pollutants, mainly proteins, are removed by membrane washing.
