New Functional Polystyrene Particles

With years of experience in the pharmaceutical and life science sectors, CD Bioparticles has announced a wide range of new Functional Polystyrene Particles with various surface functional groups such as amino, carboxyl and hydroxyl groups for covalent coupling of proteins or other ligands. The new polystyrene particles can be applied in immunoassays, analytical chemistry, and bio-nano interactions research. Polystyrene microspheres not only exhibit the general properties of polymer microspheres, such as good sphericity, large specific surface area, good surface activity, and uniform and controllable particle size, but also possess some unique characteristics, such as high rigidity, insolubility in common solvents, and non-easy biodegradability. In addition, the benzene ring of polystyrene microspheres has strong reactivity, which can carry out a series of functionalization reactions, so that the surface of the microspheres has a variety of active functional groups, and the properties of polystyrene are better exploited. Polystyrene particles provide a flexible platform for diagnostic and bioseparation applications. There are several methods for attaching biological ligands to polystyrene particles, including adsorption onto plain polystyrene particles, covalent adsorption onto surface functionalized particles, and attachment of ligands of interest onto particles precoated with binding proteins (e.g., streptavidin, protein A, or protein G). CD Bioparticles now offers multiple functional polystyrene particles with various surface functional groups, such as amino, carboxyl and hydroxyl groups for covalent coupling of proteins or other ligands.
