From Wikipedia, the free encyclopedia

Immune electron microscopy is a type of EM used to diagnose some viral infections.[1]

It is difficult.[2]

IEM was developed for identifying transmissible gastroenteritis viruses, e.g. rotavirus in feces.[3]

IEM is fast and sensitive. IEM relies on antibody-virus complexes.[4]

Procedure

[edit]
An electron micrograph of many rotavirus particles, two of which have several smaller, black spheres which appear to be attached to them
Electron micrograph of gold nanoparticles attached to rotaviruses. The small dark circular objects are gold nanoparticles coated with a monoclonal antibody specific for rotavirus protein VP6.

Application

[edit]

This was a bit of a hodgepodge:

While IEM is good for recognizing hepatitis A antigen, it's challenging to scale up.

In 1973, Feinstone et al. used IEM to find hepatitis A virus in prisoners.[6]

IEM can detect potato viruses.[7]

IEM can detect plant viruses.[8]
