Electron Microscope Grids and Case

Description (Brief):

This case held electron microscope (EM) grids used in the lab of Stanley Cohen at Stanford University. Made from tiny circles of copper mesh, EM grids are analogous to the glass slides used to mount samples for viewing under a light microscope. These grids were used to support recombinant bacteria and recombinant plasmids for study and analysis under the electron microscope. One of the grids contains a sample of Cohen and Boyer’s first recombinant plasmid. Photographic images of the first recombinant plasmids used in publications on Cohen and Boyer’s research were made from these grids.
