1.4nm Nanogold^® Secondary Antibody
& Streptavidin Conjugates

These 1.4 nm gold conjugates can be used for several different microscopy applications such as pre-embedding and post-embedding EM, labeling ultrathin cryosections, and correlative light and electron microscopy.

There are several advantages to using these small conjugates:

• They are able to penetrate up to 40 µm into cell and tissue sections;
• They can reach more antigens which give better labeling;
• They can be viewed directly in the TEM without silver enhancement;
• They give minimal background; and
• They can be enhanced with silver and viewed in the light microscope.
