Overview

• ASTM Type I Water
• Produced by reverse osmosis, ion-exchange, electro-deionization, ultrafiltration, UV treatment (UVC & 185 nm), 0.1 μm membrane filtration
• Nuclease-free, protease-free, endotoxin-free
• Suitable for molecular biology applications (qPCR, NGS etc.)
• Suitable for cell culture applications
• Produced in an ISO certified GMP laboratory
• Water system is routinely monitored for compliance with QC standards

The Norgen water purification system has been designed in conjunction with experts from Millipore Sigma. The Ultrapure NFW is purified in a two-stage process. The first stage, to produce type II water, includes pre-treatment with activated charcoal and polyphosphate, this water then undergoes reverse osmosis, electro-deionization and ion exchange to remove contaminants as well as UV treatment for disinfection. The Pure water then flows to a second system in a clean room with an additional 4 layers of purification. After passing through an additional ion exchange column, the water is then subjected to Ultrafiltration to remove particulates, bacteria, & ionic contaminants down to trace level, the water is then treated with UV light (182 nm wavelength) to break down organic matter. Lastly a second Ultrafilter for the production of pyrogen-, nuclease- and bacteria-free water at 18.2 MΩ. This water is of utmost purity and suitable for direct use in molecular biology applications such as qPCR and NGS, as well as cell culture and other applications.

Introduction

Free-circulating nucleic acids, such as tumor-specific extracellular DNA fragments and mRNAs in the blood or fetal nucleic acids in maternal blood, are present in serum or plasma usually as short fragments, <1000bp (DNA). HiPure Circulating DNA Midi Kit enables efficient purification of these circulating nucleic acids from human plasma, serum, or urine. The extracted products can be used for clinical in vitro detection.

Principle

This product is based on silica Column purification. The sample is lysed and digested with lysate and protease, DNA is released into the lysate. Transfer to an adsorption column. Nucleic acid is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, Nucleic acid was finally eluted with low-salt buffer.

Advantages

• High yield – most optimal process, free DNA (>50bp) can be obtained to the maximum extent
• High concentration – low elution volume, ensuring high nucleic acid concentration
• High purity – low alcohol binding method, completely removing inhibitor and protein pollution
• High recovery – DNA can be recovered at thelevel of PG by silica gel column purification

Storage and Stability

Proteinase K, Carrier RNA should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions. The entire kit can be stored at 2-8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature when used.

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.
