产品描述

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.

These carboxylate modified (CML) latex particles are produced by copolymerizing carboxylic acid containing polymers. The result is a latex

polymer particle with a highly charged, relatively hydrophilic and somewhat 'fluffy' surface layer. The CML particles are electrosterically stabilized,

and are therefore safe in concentrations of electrolyte up to 1M univalent salt. CML modified latex particles are negatively charged with a surface

which has a polyelectrolyte character. It is only when the pH is ~10 that all the carboxyl groups are ionized. This is a hydrophilic latex.

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)
