The adherent culture of BPAE cells featured in the digital image above was labeled with MitoTracker Red CMXRos and counterstained with SYTOX Green. Note the triplet of mitotic spindles present in the image, which are surrounded by a field of red mitochondria. Images were recorded in grayscale with a Hamamatsu ORCA-AG camera system coupled to an Olympus BX51 upright microscope equipped with bandpass emission fluorescence filter optical blocks provided by Semrock. During the processing stage, individual image channels were pseudocolored with RGB values corresponding to each of the fluorophore emission spectral profiles.
