Fluorescein - FluoroNanogold Fab' goat anti rabbit IgG (H+L) (min X Hu Sr Prot) (7004-GRP)

This unique Fab’ fragment probe contains both the 1.4 nm Nanogold® particle and fluorescein fluorophores, enabling both fluorescence and electron microscope observation of the exact same structures in a single labeling procedure. This probe is smaller than a whole IgG molecule, does not aggregate, and fluorescence quenching due to the gold particle is negligible.
