Applications of Purple Carboxyl Microspheres

CAP300-10 can be used in a variety of research and assay applications, including:

• Lateral flow assay development

• Latex agglutination tests

• Visual labeling and detection

• Immunoassay development

• Biomolecule conjugation

• Membrane-based assays

• Bead-based assays

• Particle tracing and identification

COOH Surface for Biomolecule Conjugation

CAP300-10 contains carboxyl (COOH) functional groups on the microsphere surface.

The COOH groups provide reactive sites for further functionalization and can be activated using suitable coupling chemistry such as EDC/NHS for attachment of amine-containing biomolecules.

Typical conjugation targets include:

• Antibodies

• Proteins

• Peptides

• Enzymes

The combination of a visible purple color and functional COOH surface makes CAP300-10 suitable for developing visually detectable functional microsphere assays.
