Forensic Chemistry > 3. Because proteins are a major structural and metabolic component of all living organisms, the analysis of protein samples can be useful in forensic chemistry > Electrophoresis And The Origins of Protein >
Discuss the role of electrophoresis in identifying the origins of protein and explain how this could assist the forensic chemist
- In forensic chemistry, protein analysis is useful since proteins can be found in biological samples like hair follicles, saliva, semen and blood evidences which are then linked to people involved in the scene.
- In rape-related analsyis, the presence of enzyme such as LDH isoenzyme (which is found in spermatozoa) can selectively be analyzed from the samples in presence of vaginal fluid, blood or saliva using electrophoresis.
