Gold Nanoparticle Size Optimization Panel (medium range, reactant free) transferrin Cytodiagnostics 40nm Maleimide-Activated Gold Nanoparticle

Cytodiagnostics 40nm Maleimide-Activated Gold Nanoparticle Conjugation Kit have been optimized for high efficiency one-step conjugation of thiol-containing ligands to gold nanoparticles

Composition: Carboxyl (carboxyl-PEG-thiol

This kit can also be used for determining if conjugation was successful of an antigen to the gold nanoparticles if probed with an antibody from the list above (not including in kit) prior to running the test

Surface functionality: NHS-ester (~ 1 NHS group/nm2) (10kDa PEG-spacer between gold surface and NHS-group)

This small gold nanoparticle conjugate is ideal for increasing sensitivity in immunohistochemistry protocols when used together with our silver enhancement kit for microscopy
