Learn about biomagnetic beads in one article

Magnetic beads allow easy and efficient separation of biomolecules. Use this guide to compare different surface chemical modifications and find the right type for your application.


What are magnetic beads?

Magnetic beads consist of superparamagnetic tiny iron oxide particles (20 to 30 nm), such as magnetite (Fe3O4). Superparamagnetic beads differ from ordinary ferromagnets in that they only exhibit magnetic properties in the presence of an external magnetic field. This property depends on the size of the particles in the beads and allows for the suspension and separation of the beads and any material they are bound to. Since they don't attract each other outside of a magnetic field, they can be used without worrying about unwanted clumping.


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


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


What is magnetic separation?

Magnetic separation uses a magnetic field to separate micron-sized paramagnetic particles from a 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 using magnetic beads is that nucleic acids and other biomolecules can be isolated directly from crude and various samples.


Nucleic acid extraction silicon-based magnetic beads, also known as DNA extraction magnetic beads and RNA extraction magnetic beads, are biological magnetic beads developed and produced by Geneture Medical. Have independent intellectual property rights. Nucleic acid extraction silicon-based magnetic beads use stable polymer materials as separation carriers to introduce magnetism, and then couple with ligands to form polymer microspheres containing magnetic particles. The company's nucleic acid extraction silica-based magnetic beads are suitable for DNA and RNA extraction from various biological samples. They have been widely used in plants, animals, whole blood, serum, buccal swabs, saliva, bacteria, plasmids, forensic samples, etc. For nucleic acid extraction from material, high-throughput automated DNA extraction is possible using an automated nucleic acid extractor. achieve.
