Cryo-electron tomography of native Drosophila tissues vitrified by plunge freezing

Authors Baeuerlein FJB, Pastor-Pareja JC, Fernandez-Busnadiego R Journal bioRxiv Citation bioRxiv 2021.04.14.437159. Abstract Cryo-focused ion beam (cryo-FIB) milling allows thinning vitrified cells for high resolution imaging by cryo-electron tomography (cryo-ET). However, it remains challenging to apply this workflow to tissues, as they usually require high-pressure freezing for vitrification. Here we
