5nm Maleimide-Activated Gold Nanoparticle Conjugation Kit (10 Reactions)Cytodiagnostics 5nm Maleimide Activated Gold Nanoparticle Conjugation Kit have been optimized for high efficiency one step conjugation of thiol containing ligands to gold nanoparticles. The kit contains ready to use pre made mixtures. No activation or manipulation of the gold nanoparticles is required prior to conjugation, which often results in poor performing conjugates. Simply mix your protein with the pre activated maleimide gold nanoparticles
