Dyed Microspheres

At present, the antigen detection products on the market basically adopt immunochromatographic technique. This technology shows many advantages, including simple technical requirements, fast detection capability, portability, affordability, high detection accuracy and high efficiency. One of the mainstream antibody-labeled tracers for this technique is dyed microspheres. The dyed microspheres are based on white polystyrene microspheres and are prepared by a unique internal dyeing process. The internal dyeing process makes the dye inside the microsphere, so it is not easy to leak and has a relatively stable morphological structure. The series of products are rich in color and have a variety of specifications to choose from.
