N-Boc-N-bis(PEG4-Propargyl) is a bifunctional PEG compound containing two terminal alkynes that are combined together at a Boc-protected secondary amine. Terminal alkynes are most commonly used in copper click chemistry with azides to form stable triazoles with the target molecule. The secondary amine may be deprotected under acidic conditions to allow for alkylation at that position, increasing the molecule’s structural complexity. The use of a central amine also allows for hydrogen bonding, further increasing this compound’s water solubility.

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.
