DBCO-PEG1-NHS Ester is a PEG containing molecule containing an NHS ester moiety that can react specifically and efficiently with primary amines (e.g. the side chain of lysine residues or aminosilane-coated surfaces) at neutral or slightly basic condition to form a covalent bond. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Introduction

This product is designed for purification of high-molecular-weight genomic or mitochondrial DNA from a variety of tissue and culture cells. The convenient, scalable purification procedure removes contaminants and enzyme inhibitors such as proteins and divalent cation, and purified DNA is ready for immediate use in sensitive downstream applications or for archiving.

Principles

Cells are lysed with ananionic detergent in the presence of a DNA stabilizer. The DNA stabilizer limits the activity of intracellular DNases and also DNases found elsewhere in the environment. RNA is then removed by treatment with an RNA digesting enzyme. Other contaminants, such as proteins, are removed by salt precipitation. Finally, the genomic DNA is recovered by precipitation with alcohol and dissolved in Buffer TE. Purified DNA typically has an A260/A280 ratio between 1.7 and 1.9, and is up to 200 kb in size. The DNA can be safely stored at 2-8°C, -20°C, or -80°C.

Advantages

• Safe – without phenol chloroform extraction
• Environment friendly – the reagents used are safe, non-toxic and without pollution
• High molecular weight – the molecular weight of genomic DNA is about 50-150kb
• High purity – the purified DNA has A260/280=1.8-1.9, A260/230=2.0-2.5
• Unlimited sample size – solution type operation, sample volume can be adjusted at will
• Cost performance – the most economical nucleic acid extraction technology

Storage and Stability

RNase Solution should be stored at 2-8°C upon arrival. However, short-term storage (up to 24 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.
