Immunogold Labeling in Electron Microscopy

Immunogold labeling in electron microscopy uses antibodies and tiny gold particles to find specific proteins in cells and tissues. The gold particles are very electron-dense, which means they show up clearly in electron microscope images. This gives researchers a high-resolution way to see where proteins are located and to c...

In immunogold electron microscopy, a target molecule is labeled using gold-conjugated antibodies.

The gold increases the electron scattering to give high-contrast dark spots. These spots can be distinguished from the other unlabelled structures and allow localization of the target molecule.

Direct immunolabeling uses a gold probe a...
