ENPNewswire-December 30, 2021--EPFL : Omicron's secrets revealed under a microscope

(C)2021 ENPublishing - http://www.enpublishing.co.uk

Release date- 29122021 - Thanks to the high-power electron microscopes at the Dubochet Center for Imaging (DCI), EPFL scientists were able to observe the configuration of the Omicron variant's spike protein at a near-atomic scale.

This should provide fresh insight into the mechanisms the variant uses to evade vaccines and antibodies.

Several weeks ago, Lausanne became home to some of the world's most powerful electron microscopes. They're installed at the Dubochet Center for Imaging (DCI) - a joint research facility run by EPFL, the University of Lausanne and the University of Geneva - and could turn out to be a precious ally in the fight against SARS-CoV-2, and particularly the Omicron variant that's spreading rapidly around the world.

'We're working with the virology research group headed by Didier Trono and the protein research group headed by Florence Pojer to produce a precise image of the structure of the Omicron variant's spike protein,' says Henning Stahlberg, who has established the DCI on the EPFL campus. The DCI had already produced an image of the original virus' spike protein at a resolution of 2A - the highest resolution obtained so far - enabling scientists to view individual atoms. 'We can now see exactly what mutations allow the Omicron variant to...
