How do I determine if negative stain electron microscopy is the right type of service to answer the questions I have in regard to my samples in suspension?

The process of negative staining allows an investigator an ultrastructural view of particulate specimens which are found exclusively in suspension, including virus particles, lipoprotein particles, cell fragments, bacteria, and other macromolecules.

This procedure gives an intimate morphological view of the ultrastructure of specimens in suspension, including fine-surface details and interior components. Using certain procedures, it also permits the quantitation of particles per milliliter in suspension. No other method is known by which ultrastructural details of minute specimens can be visualized with high resolution.
