Why use IMMUTEX?
Surface chemistry & ligand coupling
- IMMUTEX™ Plain Series: IMMUTEX™-Plain Series is a plain polystyrene latex particle which has no or ultra-low carboxy groups on its surface. This series is suitable for physical adsorption of antibodies or antigens.
- IMMUTEX™ Carboxy Series: IMMUTEX™-Carboxy Series is a carboxylated polystyrene latex particle suitable for covalent coupling of antibodies or antigens.
