Transmission electron microscopy services from SGS – helping you detect and quantify virus particles throughout the biopharmaceutical and vaccine manufacturing process.


During the manufacturing process, you need to ensure that your vaccine and biopharmaceuticals are free from virus particles. Our transmission electron microscopy (TEM) services, including negative staining and thin section electron microscopy techniques, help to detect adventitious agents throughout your biopharmaceutical and vaccine manufacturing process.

Why choose transmission electron microscopy services from SGS?

We can help you to:

  • Gain accurate visualization of virus particles, both in biological fluids and in vitro, through our TEM services
  • Acquire direct visualization of particle size and morphology (intra- and extra-cellular)
  • Identify viruses in biological samples
  • Observe viruses, virus-like particles, adventitious and other extraneous agents by TEM of at least 200 cell profiles
  • Identify and characterize virus particles through our negative stain electron microscopy (NSEM) testing
  • Monitor retroviral load quantities in fermenter bulk harvest material prior to the downstream purification/processing, using our negative staining techniques
