A Guide to Cryo-Electron Tomography

Cryo-electron tomography (CryoET) is used to resolve biomolecules within their cellular environment down to an unprecedented resolution below one nanometer.

U2OS cells labelled with SiR Actin, TMRE, CellEvent™, and DAPI; 13-hour time-lapse imaging; apoptosis-inducer staurosporine

Simplifying Complex Fluorescence Multiwell Plate Assays

Apoptosis, or programmed cell death, occurs during organism embryo development to eliminate unwanted cells and during healing in adults to rid the body of damaged cells and help prevent cancer.…

Formation of 3D spheroids; Time lapse acquisition over 72 hours

Efficient Long-term Time-lapse Microscopy

When doing time-lapse microscopy experiments with spheroids, there are certain challenges which can arise. As the experiments can last for several days, prolonged sample survival must be achieved…
