Hieff™ Magnetic SpeedBeads are superparamagnetic nano-Fe3O4 hydroxyl magnetic beads modified with a large number of silicon hydroxyl groups on the surface, which have the characteristics of high magnetic response, high dispersion, high suspension and high nucleic acid binding rate. Can be specifically combined with nucleic acid in a solution through hydrophobic interaction, hydrogen bonding interaction, electrostatic interaction and the like under the conditions of high salt and low pH, is not combined with other impurities (such as protein), can be quickly separated from a biological sample, and can be used for separating virus DNA/RNA in various samples such as serum/plasma/whole blood/saliva/urine, various protective solutions and the like, Plasma free DNA separation is safe and simple, and is very suitable for the automation and high-throughput extraction of nucleic acid. Application Universal Viral DNA/RNA Extration Urinary nucleic acid extraction Components Components No. Name 18405ES03 18405ES10 18405ES60 18405ES70 18405 Hieff™ Magnetic Speed Beads 1mL 10mL 100mL 500mL Specification Composition 60~70% Fe3O4、0~10% FeO and 30% SiO2 Appearance Dark brown or black Concentration 45~55 mg/ml Hydrated average particle size ~500 nm Magnetic core Fe3O4 Surface group silicon hydroxyl groups Magnetic type superparamagnetic Saturation magnetization 40-60 emu/g，in the magnetic bead preservation solution, the ordinary magnetic rack can complete the complete separation in 5-10s. Suspensibility Almost no settlement in 60 minutes Preservation solution Deionized water、0.1% Proclin 300 Notes 1. Operations such as freezing, drying and centrifugation will lead to the agglomeration of magnetic beads, which is not easy to resuspend and disperse, and affect the chemical characteristics of functional groups on the surface of magnetic beads. 2. Before using this product, be sure to fully oscillate or ultrasonically to keep the magnetic beads in a uniform suspension state. 3. This product shall be used together with magnetic separation equipment.
