Brand:  Molecular Probes™ C37268

Product Code. 11560096

Description

Microspheres (also called latex beads or latex particles) are spherical particles in the colloidal size range that are formed from an amorphous polymer such as polystyrene. Because of the way that the polystyrene chains arrange themselves in the bead, the surface is very hydrophobic in character, making these ideal materials for the adsorption of materials such as proteins.

The carboxyl latex consists of carboxyl charge-stabilized hydrophobic polystyrene microspheres. Only carboxyl groups are present on the particle surface. The particles are the carboxyl analog of the sulfate latexes. The pKa of the carboxyl group is relatively high, and consequently these particles are not suitable for work in acidic media. IDC carboxyl latexes are available in a range of sizes and surface charge densities. They may be used either for physical adsorption of antigens or antibodies, or for covalent coupling of components to the particle surface.

Microspheres Are Available in Many Sizes and Surface Functionalities

25 sizes to choose from—0.02 microns to 16 microns

20 different surface—for ready conjugation to virtually any material

Surfactant free—ultraclean

Various quantities—from milliliter to 500-liter amounts

Key Applications of Microspheres

Instrument calibration (flow cytometry, microscopy, HTS, HCS)

Flow testing (microfluidics, blood flow, water flow, and air flow)

Cell biology tracers (cell differentiation and cell tracing)

Immunoassays (agglutination tests, ELISA, particle capture, and contrast reagents)
