Latex Microspheres

Latex microspheres are composed of polystyrene as the base material. Through the unique surface modification process, the microspheres have different functional groups, and the number of functional groups is controllable. We are able to provide customized services for the preparation of microspheres of various sizes to meet the sensitivity and linear range requirements of our customers.

Latex microspheres have a wide range of applications, such as particle enhanced immune turbidity (PET), solid phase immunoassay, latex agglutination test, and microspheres capture enzyme linked immunosorbent assay, etc. We can provide large-scale microsphere production, and our capacity exceeds 100L/batch with excellent batch-to-batch consistency.

Performance characteristics:

Sufficient surface functional groups: efficiently couple with sufficient amount of target protein

Uniform diameter: stable and controllable surface functional groups: high reproducibility
