Fig. 2. Mitochondrial staining of CRK1+CRK2-deficient procyclic-form cells. CRK1+CRK2-deficient procyclic form and control cells were stained by MitotrackerTM Green FM (Mitotracker) and DAPI. The single mitochondrion extends from one end to the other of the wild-type cell. An elongated and/or branched mitochondrion is seen filling the elongated/branched posterior end of the CRK1+CRK2-deficient cell.
