Polysciences’ is pleased to expand our current line of silica microspheres with the launch of functionalized silica microspheres containing carboxyl, amine, or streptavidin surface groups.
Our silica microspheres are available with nominal diameters of 0.5µm, 1µm, and 5µm 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.
