Magnetic beads can easily and effectively separate biological molecules. Use this guide to compare different surface chemical modifications and find the type of application that is right for you.


What are magnetic beads?

Magnetic beads consist of tiny iron oxide particles (20 to 30 nm), such as magnetite (Fe3O4), which are superparamagnetic. Superparamagnetic beads differ from ordinary ferromagnets in that they display magnetism only in the presence of an external magnetic field. This property depends on the size of the particles in the beads and allows the beads and any material to which they are bound to suspend and separate. Since they don't attract each other outside the magnetic field, you don't have to worry about unnecessary clumping.


There are many kinds of magnetic beads. Different surface coatings and chemical properties give each bead its own binding properties and can be used for magnetic separation (separation and purification) of nucleic acids, proteins, or other biomolecules in a simple, effective and scalable manner.

This ease of use makes it easy to automate and suitable for various applications, including sample preparation for next-generation sequencing (NGS) and PCR, protein purification, molecular and immunodiagnostics, and even magnetically activated cell sorting (MACS).


What are magnetic beads?

Magnetic beads use magnetic fields to separate micron-sized paramagnetic particles from the suspension. In molecular biology, magnetic beads provide a simple and reliable method to purify various types of biomolecules, including genomic DNA, plasmids, mitochondrial DNA, RNA, and proteins. The main advantage of magnetic beads is that nucleic acids and other biomolecules can be directly separated from crude and various types of samples.


Silicon-based magnetic beads for nucleic acid extraction, also known as magnetic beads for DNA extraction and magnetic beads for RNA extraction, are biological magnetic beads developed and produced by gene medicine. With independent intellectual property rights. Using polymer material as a separation carrier to introduce magnetism, and then coupled with ligand to form polymer microspheres containing magnetic particles. The company's nucleic acid extraction silicon-based magnetic beads are suitable for extracting DNA and RNA from a variety of biological samples. They have been widely used in plants, animals, whole blood, serum, mouth swabs, saliva, bacteria, plasmids, forensic samples, etc. For nucleic acid extraction in the material, the use of an automatic nucleic acid extraction machine can achieve high-throughput automatic DNA extraction.
