Bangs Laboratories Fluorescent Microspheres

Visit the website

Fluorescent microspheres are a mainstay in diagnostics and life sciences research, finding use as fluorescent markers, assay substrates, and instrument standards.

In order to meet the unique performance criteria required of microparticles in these different applications we stock an extensive inventory of fluorescent microspheres and offer custom dyeing services.

Fluorescent Polymer

Our non-functionalized microspheres are suitable for coating via adsorption. See spectra for available fluorescent dyes. See TechNote 204, Adsorption to Microspheres, for a general adsorption protocol. Fluorescent polymer microspheres are available in these standard volumes: 1mL, 5mL, 10mL, and 100mL.

Fluorescent Carboxyl Polymer

Biomolecules may be covalently immobilized to carboxyl-functionalized microspheres. A general coupling protocol is provided in TechNote 205, Covalent Coupling. Fluorescent carboxyl microspheres and Europium chelate microspheres are available in these standard volumes: 1mL, 5mL, 10mL, and 100mL. See spectra for available fluorescent dyes.

Europium chelate

Our new europium products offer extremely bright fluorescence and exceptional stability, in addition to well functionalized carboxylated surfaces for the covalent attachment of ligand. See PDS 741.pdf. See spectra for available fluorescent dyes.

Fluorescent Magnetic Polymer

Both Encapsulated (ME catalog codes) and Classical (MC catalog codes) superparamagnetic microspheres are synthesized using a process that results in the distribution of iron oxide crystals throughout the polymer matrix. For specific information on the use of fluorescent magnetic particles for cell labeling & tracking, see TSD 0748. The surfaces of Encapsulated magnetic microspheres are expected to be free of iron oxide, while the Classical version will have some exposed iron oxide. COMPEL microspheres (UMC catalog codes) are highly uniform and spherical. Fluorescent magnetic microspheres are available in these standard volumes: 1mL, 5mL, 10mL, and 100mL. See spectra for available fluorescent dyes.
