Alan Prescott has been awarded third place in the annual British Society for Cell Biology (BSCB) image competition. His confocal image is of a cultured mouse embryo fibroblast from the mito-QC mouse. Mitochondria express both eGFP and mCherry but in lysosomes the eGFP, green fluorescence is quenched. Bright red dots are mitolysosomes. The nucleus is DAPI stained, blue. The image features in the Journal of Cell Biology publication from Ian Ganley's lab (McWilliams et al., (2016) JCB, 214(3).
