Cytodiagnostics Streptavidin covalently conjugated gold nanoparticles can be used for secondary detection of biotinylated probes in assays such as lateral and vertical flow assays, immunoblotting, ELISA, light microscopy and electron microscopy applications.
When compared to traditional conjugates utilizing passive adsorption, covalent conjugation provides:
- Improved stability of the final conjugate
- Higher sensitivity in assays
- Reduced background and non-specific binding events
- Improved control over the final loading of protein onto the gold’s surface
Streptavidin gold conjugates can be used for convenient and fast conjugation of any biotinylated ligand such as antibodies and oligonucleotides to the gold surface.
