Invitrogen™ Aliphatic Amine Latex Beads, 2% w/v, 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 aliphatic amine latex has a high density of amine groups attached to the terminus of an aliphatic six-carbon spacer arm. This product can be used to covalently couple proteins. Location of the amine at the end of the spacer arm minimizes difficulties with steric hindrance and conformation since the group has a greater freedom to rotate. In addition, spacer arms improve the kinetics of latex agglutination reactions. The particles are stabilized by the positively-charged amine groups under low to neutral pH conditions. Care should be taken not to use them under high pH.

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
