Streptavidin-coated beads as solid support


Magnetic particles are used as a solid support phase in immunoassays. MagSi-STA are superparamagnetic silica beads with a surface coating of streptavidin for use with biotinylated antibodies.

MagSi-S COOH | MagSi-S Tosyl

MagSi-S COOH and MagSi-S Tosyl are the most suited surface modifications to use in conjunction with immunoassay applications.
