Product Overview
CFP400-10 Carboxyl Purple Fluorescent Microspheres are 400 nm fluorescent microspheres functionalized with reactive carboxyl (-COOH) groups.
Supplied as a 1% suspension, these microspheres provide purple fluorescence with an excitation wavelength of 545 nm and an emission wavelength of 615 nm.
The carboxyl-functionalized surface provides reactive sites for biomolecule immobilization and conjugation, making CFP400-10 suitable for fluorescence-based assays, biomolecule labeling, fluorescence imaging, particle tracking and diagnostic research.

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.
