Our high degree of specialization and expertise in microparticle technology enabled us to concentrate on all aspects of carboxyl microspheres. An enormous amount of research work has been focused on the development of every possible carboxyl microsphere for diagnostic assays. Within each size, we offer different levels of functionality to provide a range of selectivity, sensitivity, and specificity as desired for each application.

• More than 100 products - various sizes and surface charge densities
• Optimized levels of carboxyl and sulfate groups for maximum coupling efficiency
• Very uniform surface morphology and even distribution of functional groups
• Can be used without precleaning for most applications
• Highly uniform, stable, and reproducible
• Fluorescent and Dyed microspheres: Available in selected sizes

Near-Soap-Free? Carboxyl Microspheres

PolyMicrospheres innovative process technology has led to the development of a novel product line, “Near-Soap-Free" carboxyl microspheres with high MW. The surface chemistry is similar to conventional microspheres, very uniform and stable, but with very little surfactants.

• Better than soap-free microparticles with no residual monomer and with optimum amount of sulfate groups
• The very little surfactant level with a novel process technology provides stability and uniformity throughout the polymerization
• Surfactant levels of the products are very low (from 0.01% to 0.05%) and do not require clean up
• Optimized levels of carboxyl groups and uniform surface morphology for maximum coupling efficiency
• Highly uniform, stable, and reproducible
• Fluorescent and Dyed microspheres: Available in selected sizes
• We also make it to your exact specs

SpaceLink? Carboxyl Microspheres

SpaceLink? Carboxyl Microspheres are perfect immunodiagnostic reagent particles with a spacer-linker already attached to the microspheres. The length of the flexible spacer arm is ~10A°. The end of the spacer arm has a carboxyl group for covalent attachment of ligands. The second generation of SpaceLink microspheres have been developed and tested at ?-sites for best coupling efficiency.

The benefits of SpaceLink? Carboxyl microspheres include:

• Almost all of the ligands coupled to the microspheres will be in an active form
• Conformational changes or orientation problems of the ligands are minimized when the ligands are located away from the surface of the particles
• Higher level of sensitivity compared to direct surface coupling; Lesser amount of ligand needed to get the required sensitivity
• The flexible spacer arms improve the kinetics of agglutination reactions and reactivity of each coupled ligand by keeping the ligands away from the surface of the particles
• Antigen/antibody recognition sites line up much more easily
• The flexible spacer arms greatly reduce steric hindrance problems
• We also make it to your exact specs
• Also available: SpaceLink Hydroxyl microspheres
