Cells were then processed for imaging using dual labeling for ARL2 (green, left) and either cytochrome c (top row, middle panel) or HSP60 (lower two rows, middle panels), as markers of the IMS and matrix, respectively. Merged images are shown on the far right in each case.</p> 2014-06-09 03:35:59 Biochemistry Bioenergetics Energy-producing organelles mitochondria cell biology Signal transduction cell signaling GTPase signaling Cellular structures and organelles arl2 localizes mitochondrial
