Researchers performing cryo-EM experiments can acquire the training to make their own cryo-EM and negative-stain grids, and collect and process their own high-resolution data. We also offer sample ...

To ensure that the tissue structures of biological samples are easily recognisable under the electron microscope, they are treated with a staining agent. The standard staining agent for this is ...

For centuries, scientists have used microscopes to magnify and peer into a world invisible to the naked eye. The earliest instruments were simple lens-filled tubes, the best of which revealed the ...
