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.

Magnetic Beads (tRNA Purification)
Solid Phase Reversible Immobilization magnetic beads has been used for nucleic acids purification because they are effective, simple, and fast. The carboxyl groups coated beads are paramagnetic particles that reversibly bind to nucleic acid. However, there is a drawback for magnetic beads that it can only purify DNA/RNA that are 100 base pairs or longer. tRNA and other DNA/RNA fragments shorter than 100 base pairs are not effectively recovered. We have developed Magnetic Beads (tRNA Purification) to overcome the hurdle.
The Magnetic Beads (tRNA Purification) solves the tRNA and short DNA/RNA purification problem. The beads with our proprietary technology purify tRNA effectively by removing impurities and unwanted components such as dNTPs, detergents, salts, proteins, and other contaminants. The magnetic bead reagents can be used for oligo (>70 nt) applications.
Workflow without large RNA/DNA contamination
In the case of samples contaminated with RNA/DNA such as rRNA and DNA, our magnetic beads can effectively remove RNA/DNA that are 180 nt and larger. Purified tRNA are ideal for applications requiring high quality, as the fragments are free of impurities and contaminants.
Workflow with large RNA/DNA contamination
Comparison of tRNA and 70 nt oligos recovery. BioDynami beads (tRNA purification) successfully recovered DNA fragments both yeast tRNA and 70 nt oligos.
Recovery of tRNA and 70 nt oligos with BioDynami magnetic Beads (tRNA Purification). Yeast tRNA and 70 nt oligos were used as input. Input and recovered oligos were quantified with ssDNA Quantification kit (BioDynami Cat. # 40043) and RNA Quantification kit (BioDynami Cat. # 40044).
