Experimental investigations in post-mortem protein degradation.

Samples of thoracic fluid were obtained at regular intervals from the putrefying bodies of dead dogs. For quantitative estimation of the proteins two-dimensional immunoelectrophoresis was employed and for the amino acids and amines two-dimensional thin-layer chromatography. The results lead to speculation that the initially lagging proteolytic changes are due to catalysis of autoenzymes, whereas bacteriological processes are responsible for a distinct acceleration from the 20th day after death.
