IVD Test Reagent/Kits, Electron Microscopy, Stain, Ruthenium Tetroxide

Definition : Electron microscopy stains designed to provide contrast to the specimen using ruthenium tetroxide. These electron microscopy stains are quite volatile and aggressive oxidants. Ruthenium tetroxide stains saturated and unsaturated polymer materials as well as stabilizing thin sections under the bombardment of the electron beam; some can produce either a positive or a negative stain. They are used as fixation/staining agents for electron microscopy.

Electron Microscopy Sciences (EMS)

Company Type: Parent

Electron Microscopy Sciences has been specializing in the manufacturing, preparation, and distribution of only the highest quality chemicals, supplies, and equipment, for microscopy, and all of its related fields.

Ladd Research

Company Type: Parent

Ladd Research was organized in 1954 by Margaret and Bill Ladd to develop and supply products for the growing field of electron microscopy. In the 1930's, Margaret and Bill had worked on the first electron microscopy built in North America at the University of Toronto. At the start of World War II, they moved to the United States to continue their research. In 1954 Ladd Research Industries was formed.

Polysciences Inc

Company Type: Parent

The company was founded in 1961 to provide sample preparation products for electron microscopy as nano-scale samples were starting to reveal new knowledge. Embedding products were added for histology (the study of tissue) applications soon after, enabling tissue embedment in plastic blocks, in addition to paraffin. Dyes and stains were developed to implement better visualization of the samples. In cooperation with federal agencies, monodisperse polymeric microspheres were developed for diagnostic kit applications.
