2.3.5. Sarcomere lengthThe sheared cores used for WBSF at 1 d postmortem were kept forsarcomere length measurement (Wheeler et al., 2002). Six fibers bundles were taken from each core using a fine tip tweezer and then placedon a microscope slide with a drop of fresh buffer solution containing0.2 M Sucrose in 0.1 M NaHPO4 buffered at pH 7.2. Sarcomere lengthwas measured using a helium neon laser diffraction unit (05-LHR-021,Melles Griot, Carlsbad, CA, USA) and calculated as described byCross et al. (1981).
