White Polystyrene Microspheres
Characteristic
White polystyrene microspheres are prepared from polystyrene by emulsion polymerization, and are available in a variety of sizes, ranging in size from 0.05 – 50 μm, with uniform particle size.
Features
Perfect spherical, highly uniform particle size(CV＜3%)
High chemical stability
Good monodispersity
Application
Polystyrene microspheres with no functional groups on the surface are suitable for binding antigens and antibodies by physical adsorption; Polystyrene microspheres with modified carboxyl groups on the surface can be coupled to ligands such as antigens/haptens, antibodies, peptides and nucleic acid probes by covalent bonding manner, providing ideal materials for immunodiagnosis and biological separation. It provides an ideal material for biological separation. We can provide customized services such as a variety of particle sizes and surface groups to meet diverse needs.
Storage
Store at 2 – 8°C, do not freeze.
