We will dye for you!

Visibly dyed microspheres are frequently used in lateral flow tests and "latex" agglutination tests. Our polystyrene microspheres are impregnated with vibrant dyes for optimal visualization. See the below color palette for a representation of our standard colors. Non-functionalized and functionalized versions are available to support adsorption and covalent binding strategies.

Dyed polystyrene

Our non-functionalized microspheres are suitable for coating with antibody or other large proteins via adsorption. See TechNote 204, Adsorption to Microspheres, for a general adsorption protocol. Unless noted otherwise, these visibly dyed microspheres are supplied as a 5% solids suspension (w/w) and are available in these standard amounts: 0.5g, 1.0g, 1.5g, and 5.0g.

Dyed Carboxyl polystyrene

Biomolecules may be covalently immobilized to carboxyl-functionalized microspheres. A general coupling protocol is provided within TechNote 205, Covalent Coupling. Our dyed carboxyl microspheres are impregnated with vibrant dyes for optimal visualization. See our color palette for a representation of our standard colors. Unless noted otherwise, they are supplied as a 5% solids suspension (w/w) and are available in four standard volumes: 0.5g, 1.0g, 1.5g, and 5.0g.
