Latex microspheres

Category Description :

Latex microspheres:

This series of microspheres are based on polystyrene material. Through unique surface modification process, microspheres carry with different functional groups, to achieve a controllable amount of functional groups. At the same time, we can prepare microspheres of various particle sizes according to the application directions to meet the diverse needs of customers. Besides, the most capacity of our products can reach more than 100 L in single batch, with a lower batch difference, providing stable high-quality raw materials for the large-scale production of customers.

Different surface modification process enables users to conjugate monoclonal antibody, polyclonal antibody, antigen and hapten and other protein molecules or molecular biological tools with microsphere surface by means of passive adsorption or covalent coupling, to prepare kinds of diagnostic reagents and related intermediates. This series of products have been used in the development of diagnostic reagents in large-scale, including “particles enhanced immunoturbidimetry (PET)", "capture ELISA", "agglutination test" and "solid phase immunoassays".

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.
