White paper: A comparative study of MiniTEM versus DLS and NTA.

This study compares the performance and the ability to detect the Adeno associated virus particles (AAV) of interest and distinguish them from contaminating proteasomes.

Objective Characterization of Liposomes

White paper presenting how Liposomal physicochemical characteristics are objectively and accurately measured by using cryo Transmission Electron Microscopy (TEM) in combination with Vironova image analysis software.

ProViz: A new software for easy and intuitive visualisation and analysis of electron tomograms with low signal-to-noise ratio.

Visual understanding is a key aspect when studying electron tomography data-sets, aside quantitative assessments such as registration of high-resolution structures. In a recently published article, Vironova CTO Ida-Maria Sintorn and co-authors present the free software tool ProViz (Protein Visualization) for visualisation and template matching in electron tomograms of biological samples.
