Magnetic Immunoassays (MIA) use MagSIGNAL-STA 300 or MagSIGNAL-COOH 300 beads as detection labels instead of conventional enzymes, fluorophores or luminescent molecules.

MagSi-STA are magnetic silica particles with high quality streptavidin covalently attached to the bead surface. Applications include immunoassays and capture or purification of biotinylated molecules. The MagSi-STA Trial kit allows the screening of different types of streptavidin in parallel.
