Tailoring solutions
to meet market demands

At QuTEM, we use transmission electron microscopy (TEM), including cryogenic TEM (cryoTEM) and negative stain TEM (nsTEM), to visualize and resolve fine details of nanoparticles. We empower you with reliable and traceable data to help you to make better-informed decisions. Check out the following highlights of our services.

Genome length determination

We have developed and validated a method leveraging the relationship between particle density and genome length to determine the encapsulation of genetic material within viral vectors.
