Press Release Body = Warrington, PA, August 2006 - Polysciences, Inc., a leading
manufacturer of laboratory
supplies and specialty monomers/polymers for life sciences, medical research and
industry,
announces the availability of new functionalized silica microspheres containing
carboxylic
acid, amine or streptavidin groups.
Functionalized silica microspheres are available with nominal diameters of 0.5
micron, 1 micron
and 5 micron to allow the researcher to tailor his/her product design for specific
assays. The
carboxyl functional and amine functional materials are supplied as 100% solids while
the
streptavidin modified microspheres are offered as a 1% dispersion in water.
\"Silica microspheres offer unique characteristics compared to their polymer
counterparts. Silica
microspheres offer a lower refractive index than polystyrene, a greater density for
easier settling,
and a hydrophilic surface that reduces non-specific binding of hydrophobic ligands.
Our new
functionalized silica products provide a convenient means for covalent
immobilization through
carboxyl or amine groups or affinity binding of biotinylated ligands.\" said Chad
Owen, Particles
Division Vice President, Polysciences, Inc.
