After fixation, the lumbar spinal cords with posterior roots were removed en bloc and each was dissected into three gross samples (A, B and C): the transverse section with lumbar spinal cord of L3 (sample A) for light microscopic examination and TUNEL staining (see TUNEL staining for apoptosis below), the posterior corner section of L3 (sample B), and the posterior roots section of L3 (sample C) for electron microscopic examination.
The utility and relative simplicity of the TUNEL assay makes it useful for an inquirybased laboratory.

TUNEL assays and 2-color flow cytometry were used to distinguish apoptotic hemocytes from nonapoptotic cells and to correlate apoptosis frequencies with cell cycle stage as estimated by relative cellular DNA contents (Fig.
