Magnetic microspheres

Category Description :

Magnetic microspheres:

This series of magnetic microsphere products are designed for extraction and purification of biological samples and test.

Microspheres for extraction and purification use have a core-shell structure, featured of high magnetic content and large surface area, adsorbing a large number of functional groups or modified proteins to the surface. High magnetic content and moderate density ensure that the microspheres have good magnetic response speed and excellent re-suspension performance under the function of a magnetic field, and are suitable for different types of automation equipment requirements.

Magnetic microspheres for detection use can be modified by streptavidin on the surface, having a characteristic of specifically binding with biotin. Users need only to couple biotin with target antibody (or antigen/hapten), those biomolecules can be cross-linked to microsphere surface, easy to use. At the same time, high magnetic content and moderate density ensure that the microspheres have good magnetic response speed and excellent re-suspension performance under the function of a magnetic field, and are suitable for different types of automation equipment requirements.

This series of products can be long-term stored at 2-8°C. However, the freezing, direct drying and drying and other operations will result in irreversible microsphere agglomeration, leading to reduction in biological application performance.
