What happens if there is a delay in fixation?

Delaying fixation allows the tissue’s own enzymes to keep breaking down cellular components after death, leading to autolysis—the self-digestion of cells and tissues. Fixation is needed to inactivate these enzymes and preserve structure by cross-linking proteins, so when fixation is delayed the architecture becomes distorted and cellular detail is lost as digestion proceeds. Other options aren’t direct results of postponing fixation: hyperpigmentation relates to pigment accumulation rather than enzyme-driven degradation; calcification is mineral deposition that can occur under different conditions; shrinking is more about processing artifacts than the immediate effect of fixation timing.
