Thermo Fisher Scientific Aldehyde/Amidine Latex Beads, 4% w/v, 0.3 μm

Invitrogen™ Aldehyde/Amidine Latex Beads, 4% w/v, 0.3 μm

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.

This aldehyde/amidine latex is similar to aldehyde/sulfate latex particles, but with a positively charged amidine functional group to provide colloidal stability. This latex is not sensitive to multivalent cations.

Microspheres Are Available in Many Sizes and Surface Functionalities

• 25 sizes to choose from — 0.02 μm to 16 μm
• 20 different surface types — ready for 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)
