With these forensic technologies, crime scene investigators, forensic scientists, and police officers can quickly and easily compare a fingerprint at a crime scene with an extensive virtual database. One aspect of proteomes that differs from DNA is that they change over time, offering scientists valuable insights into a victims age or other environmental factors at the time of death that are impossible to detect through other methods. Most forensic scientists and crime lab technicians use DNA profiling to identify criminals and victims using trace evidence like hair or skin samples. Like many other immunological tests, this method works by the antigen-antibody reaction. Immunochromatography is one of the most useful methods and uses strip tests to detect body fluids in stains and trace the source of origin.

The immunochromatography assay (ICA), also known as the lateral flow test, is a simple . This test applies the principle of sandwich ELISA and can be performed on a strip set-up like a pregnancy test for HCG mentioned earlier. Still, most people dont know exactly what DNA sequencers are and how they may be used. Did u try to use external powers for studying? Multiplex detection format is very useful in clinical diagnosis where multiple analytes which are inter-dependent in deciding about the stage of a disease are to be detected. Body fluid identification is a substantial part of forensic trace analyses, reads the article. For ICA, two varieties of specific antibodies are used against the antigen.
