Optical microscopy has traditionally been an indispensable tool in cell biology studies. In fact, one of the main challenges in oncology research is the study of specific markers, expression patterns or individual cells in the tumour environment.

The Confocal Microscopy Unit provides CNIO’s Research Groups with all the standard methodologies as well as the latest advances in microscopy, offering access to state-of-the-art equipment and software packages related to confocal microscopy, including technical and scientific advice and support to CNIO scientists. The Unit is actively involved in developing, testing, and implementing new microscopy technologies, tools and imaging applications that could be of interest to CNIO Research Groups. Training activities are also an essential component of our mission.
