Description

We offer standardized and labeled polystyrene (PS) and cross-linked polystyrene/divinylbenzene (PS/DVB) microspheres, suitable for use as standards or labels for labeling, or for protein encapsulation through adsorption for diagnostic testing and analysis. Functionalized polystyrene microspheres are suitable for the covalent fixation of proteins, peptides, and nucleic acids. We provide products with different particle sizes and surface chemical properties to meet customers' needs for reagent sensitivity and assay range. The particle size coefficient of variation (C.V) typically does not exceed 5-10%, and most products are suspensions in aqueous media. 

Features

• Selectable particle size range: 20nm-1000μm, customizable upon request.
• Uniform particle size distribution.
• Diverse surface chemical properties.
• Different levels of hydroxyl functional group density.
• Other functional groups can be utilized to control detection sensitivity and assay range.
• Microspheres suitable for high sensitivity assay development are available.

Polystyrene-based microspheres also feature visible staining with red dye microspheres.
