Cytodiagnostics amine functionalized gold nanorods have precisely engineered surface chemistry that allows for simple and efficient binding to moieties that react with primary amines. An example of such a reaction would be a conjugation to a protein or antibody that has been tagged NHS, which would yield a covalent link between the gold nanoparticle surface and the protein.
This permanent linkage allows for further downstream applications such as monitoring the distribution of the now-tagged molecule.
Cytodiagnostics amine gold nanorods are available with 3 different aspect ratios, with maxima of 650nm, 700nm, or 770nm, and are also available with 2 different spacer lengths (3 kDa and 5 kDa).
This provides the customer with the necessary tools to fully optimize their experiment.
