Beads for Magnetic Immunoassays

MagSIGNAL

Magnetic immunoassays (MIA) use magnetic beads as detection labels instead of conventional enzymes, fluorophores, or luminescent molecules. The presence of magnetic beads is detected by a magnetic reader which measures the magnetic field induced by the beads. The signal measured by the magnetometer is proportional to the analyte. MagSIGNAL are superparamagnetic beads with a mean diameter of 300 nm and are suitable for magnetic immunoassays in a variety of formats such as conventional lateral flow tests, microfluidic applications and biochips.

MagSIGNAL-STA 300

MagSIGNALSuperparamagnetic particles of 300 nm with high quality streptavidin covalently attached to the bead surface. Intended for use with biotinylated antibodies as a detection label in magnetic immunoassays, or as solid support phase in immunoassays with other readout techniques.
