The procedures for the Preparation of regulatory proteins of myofibrill were developed and postmortem changes in the regulatory proteins of myofibrill were investigated. Both the physiological property and molecular shape of ${\alpha}-actinin$ from pre-rigor muscle did not differ from those of ${\alpha}-actinin$ from post-rigor muscle. On the other hand, although tropomyosin of myofibril changed negligibly during the post-mortem storage of muscle, troponin of myofibril changed remarkably.
