DRP2 and transient ischemic attack: To do so, we studied DRP2 in 4E-BP2 immunoprecipitates by two-dimensional (2D) fluorescence difference in gel electrophoresis (DIGE), confirming the identification of DRP2 isoforms by matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) mass spectrometry (MS) and Western blotting in the cerebral cortex and hippocampal CA1 region, after transient cerebral ischemia.
