One aspect of proteomes that differs from DNA is that they change over time, offering scientists valuable insights into a victim’s age or other environmental factors at the time of death that are impossible to detect through other methods.
Scientists can find proteomes in blood, bones, and other biological materials and analyze them to find answers, such as if a victim came in contact with an otherwise undetectable venom or matching a severely degraded body fluid sample to a perpetrator.
