CryoEM Sandwiches (IMAGE) DOE/SLAC National Accelerator Laboratory Caption Cryo-EM reconstructions of KIX (red) sandwiched between an MBP outer shell (purple) and an apoferritin inner shell (blue). The sandwiching technique helped researchers get the best look yet of KIX, a potential target for treating acute myeloid leukemia.
