Serialized On-grid Lift-In Sectioning for Tomography (SOLIST)
Cryo-focused ion beam milling has enabled groundbreaking structural discoveries in native cells. Progress toward medically relevant applications, however, has been slow. We here present an adaptation of the cryo-lift out procedure for Serialized On-grid Lift-In Sectioning for Tomography (SOLIST), which increases throughput, reduces ice contamination, and enhances sample stability. With these improvements, new specimens, ranging from high-pressure frozen reconstituted LLPS droplets to human forebrain organoids, are accessible to cryo-electron tomography.
