Notes:
FSR (fragmented sarcoplasmic reticulum) isolated from chicken breast muscle (Pectoralis major) at 0 hr, 48 hr and 7 day postmortem was purified using linear density gradient centrifugation. The Ca++accumulating ability of the FSR was found to increase with postmortem aging. No loss in ATPase activity was noted nor was any significant change observed in the SDS-gel electrophoresis patterns of the proteins with postmortem aging. The FSR from the aged muscle contained a higher proportion of phospholipids These studies indicate that the Ca++ sequestering properties of sarcoplasmic reticulum from chicken breast muscle are not impaired during postmortem aging.
