Carboxyl-Functionalized Surface

CFP400-10 features reactive carboxyl (-COOH) groups on the microsphere surface.

The carboxyl-functionalized surface provides reactive sites for covalent attachment of biomolecules and makes the particles suitable for applications requiring surface conjugation rather than fluorescence detection alone.

EDC/NHS Biomolecule Conjugation

The surface carboxyl groups can be activated using EDC/NHS coupling chemistry for covalent conjugation with amine-containing biomolecules.

Suitable conjugation targets can include:

  • Antibodies

  • Proteins

  • Peptides

  • Other amine-containing biomolecules

This combination of fluorescence and reactive surface chemistry makes CFP400-10 suitable for developing functional fluorescent particle systems.

Applications

CFP400-10 Carboxyl Purple Fluorescent Microspheres can be used for:

  • Biomolecule conjugation

  • Antibody conjugation

  • Protein immobilization

  • Fluorescence-based assays

  • Immunoassay development

  • Fluorescence imaging

  • Fluorescence microscopy

  • Particle tracking

  • Biomolecule labeling

  • Diagnostic research

  • Biosensor development

  • Life science research

Carboxyl Purple Fluorescent Microspheres for Assay Development

CFP400-10 combines a defined 400 nm particle size, purple fluorescence and reactive carboxyl surface chemistry.

Unlike plain fluorescent particles used primarily as optical markers, carboxyl-functionalized fluorescent microspheres provide reactive surface groups for biomolecule conjugation.

This makes CFP400-10 suitable for developing particle-based fluorescence assays where both fluorescence detection and biomolecule immobilization are required.

Carboxyl Purple Fluorescent Microspheres for Biomolecule Labeling

The combination of Ex 545 nm / Em 615 nm fluorescence and surface carboxyl (-COOH) groups enables CFP400-10 to be evaluated for biomolecule labeling applications.

Antibodies, proteins, peptides and other suitable amine-containing biomolecules can be covalently attached through appropriate carboxyl coupling chemistry.

Fluorescence Imaging and Particle Tracking

With a defined particle diameter of 400 nm and purple fluorescence, CFP400-10 can also be used in compatible fluorescence imaging and particle tracking applications.

Potential research applications include fluorescence microscopy, particle localization, particle distribution studies and fluorescence-based analytical methods.

Product Advantages

CFP400-10 combines:

  • 400 nm uniform fluorescent microspheres

  • Reactive carboxyl (-COOH) surface

  • Purple fluorescence

  • Ex 545 nm / Em 615 nm

  • 1% solid content

  • Biomolecule conjugation capability

  • EDC/NHS coupling compatibility

  • Fluorescence detection and surface functionalization in one particle platform

The combination of fluorescent properties and reactive carboxyl groups makes CFP400-10 more suitable for functional assay development than non-functionalized fluorescent particles.
