Introduction
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.

Compatible with most DNA and RNA isolation methods
Norgen’s Total Nucleic Acid Preservation Tubes Dx are designed for ambient preservation and transport of total nucleic acids (DNA and RNA) from samples collected using a swab. The Total Nucleic Acid Preservation Tubes contain Norgen’s Total Nucleic Acid Preservative in a liquid format. The user simply collects the specimen using a sterile nylon flocked swab (not provided), and then transfers the swab into the Total Nucleic Acid Preservative. The 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 Total Nucleic Acid 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 preservative allow DNA samples to be stored at room temperature for over 4 months and RNA samples to be stored at room temperature for over 2 months. This kit is ideal for collecting and preserving nasal and oral swab samples for in vitro diagnostic use for medical purposes. This kit can be used to preserve viral RNA, including SARs-CoV-2 RNA for detection of COVID-19.
Norgen’s Total Nucleic Acid Preservation Tubes Dx are intended for use by professional users such as technicians, physicians and biologists experienced and trained in molecular biological techniques.
Norgen’s Total Nucleic Acid Preservation Tubes Dx do not provide a diagnostic result. It is the sole responsibility of the user to use and validate these devices in conjunction with a downstream in vitro diagnostic assay.
Shelf Life and HandlingThe tubes should be kept tightly sealed and stored at room temperature for up to 1 year without any reduction in performance (The collection due date is written on the device label and the kit box label).Once collected, RNA is stable for up to 2 months and DNA is stable for up to 4 months when the tubes are kept tightly sealed and stored at room temperature.
The Saxitoxin (PSP) ELISA Kit is a competitive ELISA for the quantitative analysis of saxitoxin in shellfish samples. This kit can be used for rapid test of Saxition in samples such as mussels and lobster tomalley.
The Saxitoxin (PSP) ELISA Kit uses a polyclonal antibody that binds both saxitoxin and a Saxitoxin-enzyme conjugate. Saxitoxin in the sample competes with the Saxitoxin-enzyme conjugate for a limited number of antibody binding sites.
