Carboxyl latex microspheres

This series of latex microspheres is composed of polystyrene as the base material. Through the unique surface modification process, the microsphere is made with different functional groups, and the number of functional groups is controllable. We are able to provide customized services to prepare microspheres of various sizes to meet customer requirements for sensitivity and linear range. This series of latex microspheres has a wide range of applications, such as "Particle enhanced immunoturbidimetry (PET)", "solid phase immunoassay", "latex agglutination test", and "microsphere capture enzyme-linked immunosorbent assay".

The single batch production capacity of this series of latex microsphere products can reach more than 100L, and the difference between batches is small, which can provide high-quality products for large-scale production of customers.
