Tailoring solutions
to meet market demands

At QuTEM, we use transmission electron microscopy (TEM), including cryogenic TEM (cryoTEM), negative stain TEM (nsTEM), as well as our proprietary method, QuTEM, 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.

CryoTEM vs QuTEM method

In this article, our collaborator highlighted QuTEM for its ability to classify particles as empty, partial, or full and provide particle-level insight, giving developers visibility into both the quantity and type of partials in a sample.

North America satellite laboratory

QuTEM and Boston University are collaborating to provide localized, high-speed AAV analysis for North American gene therapy developers.

GMP

QuTEM holds GMP Certificates and Manufacturing Permits from the Swedish Medical Products Agency, authorizing QuTEM to perform critical quality control TEM analysis of medicinal and investigational medicinal products.
