The weapon is our monodisperse magnetic silica beads which is used in the step of RNA extraction from collected samples.
EPRUI-MagSi: Silica magnetic beads are specially designed for extraction and purification of DNA/RNA. There are rich silanol groups on the surface which can specific binding nucleic acids in solution through hydrophobic interaction, hydrogen bonding and electrostatic interaction under high salt and low pH condition.
Without binding with other impurities (such as proteins), EPRUI-MagSi can quickly separate DNA/RNA from biological samples. The operation is safe and simple, and is easy for automatic and high throughput extraction of nucleic acid.
EPRUI-MagSi is monodisperse silica magnetic bead with narrow particle size distribution and excellent dispersion property compared with traditional multinuclear magnetic beads, EPRUI-MagSi is a single nuclear magnetic bead with silica layer thickness of about 1/20 of the size of the magnetic bead.
The magnetic content is more than 95% which greatly improves the magnetic responsiveness of the magnetic beads, and the complete magnetic separation time is less than 5 seconds. Based on the excellent characteristics of EPRUI-MagSi, which is very easy to perform rapid separation and rapid re-suspension dispersion after withdrawing magnetic field.
It is especially suitable for automated nucleic acid extractor, which greatly shorten the operation time of nucleic acid extraction process. Due to the narrow particle size distribution of EPRUI’s silica magnetic beads, the batch differences during nucleic acid extraction can be significantly reduced, which provides guarantee to the reproductivity of in vitro molecular diagnosis and subsequent gene manipulation in molecular biology based on nucleic acid extraction.
