– The streptavidin–biotin (SA-Biotin) system is known to have a very high affinity (Kd= 10^-15) and specificity, and is widely used in biochemical field. TargetMol Mag Beads Streptavidin covalently connects SA to the beads surface through protein-protein coupling method. This enables efficient binding of biotinylated antibodies, nucleic acids, and proteins. The product combines superparamagnetic advantages with unique features including uniform size and regular morphology, facilitating the rapid capture of target molecules and magnetic separation. This product can be used with automated equipment for high-throughput technology.
