VDO Biotech's carboxyl latex microspheres are made of polystyrene. Through our proprietary surface coating process, carboxyl groups are added to the microspheres in controlled amounts. We can also provide microspheres with customized particle sizes and functional groups to meet customers' specific needs for sensitivity and linear range. The carboxyl latex microspheres are widely used for different applications, such as particle enhanced immunoturbidimetry (PET), latex agglutination test, and microsphere capture enzyme-linked immunosorbent assay, etc. The production capacity of carboxyl latex microspheres exceeds 100L/batch, with batch-to-batch consistency, which ensures high-quality products for customers' large-scale production.
