Estapor® White Microspheres

Dyed microspheres are extremely uniform and are dyed internally (their surface properties are unchanged), insuring maximum color brilliance and preventing dye leaching in water or aqueous buffers.

These photostable fluorescent microspheres have been specifically developed and patented by Estapor®. Made in polystyrene (PS) or in polyvinyltoluene (PVT), our fluorescent microspheres are monodisperse and uniform, ranging in size from 20 nm to 4 μm. Our fluorescent products are also available as plain or functionalized microspheres. To prevent dyes leaching and to provide the maximum of active surface, the fluorescent dyes are physically and irreversibly entrapped inside the microspheres.

The use of magnetic microspheres is a well established alternative to conventional chromatography resins in automated high throughput protocols replacing centrifugation, organic solvents and filtration by simple and rapid magnetic separation. Our product portfolio of superparamagnetic microspheres is very large in terms of size, surface and ferrite content. These magnetic microspheres have the appearance of a dark brown liquid.

This line of microspheres includes Streptavidin, anti-mouse IgG, anti-human IgG, Protein A and Protein G coated microspheres, allowing researchers to optimize any Bioseparation, Biopurification or Biodetection applications, without sacrificing sensitivity and ease of use.
