Thermo Fisher Scientific Aliphatic Amine Latex Beads, 2% w/v, 0.3 μm

Invitrogen™ Aliphatic Amine Latex Beads, 2% w/v, 0.3 μm

Microspheres (also called latex beads or latex particles) are spherical particles in the colloidal size range formed from amorphous polymers such as polystyrene. Because of the arrangement of polystyrene chains, the surface is highly hydrophobic, making these beads ideal for 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. It is suitable for covalent coupling of proteins. The location of the amine at the end of the spacer arm minimizes steric hindrance and allows greater rotational freedom, improving reaction kinetics. Spacer arms also enhance the kinetics of latex agglutination reactions. The particles are stabilized by positively charged amine groups under low to neutral pH conditions; avoid use under high pH.

Microsphere Features

• 25 sizes available (0.02 μm to 16 μm)
