Forensic electrophoresis is one of the most important methods of laboratory analysis, and has allowed highly relevant research results; it is a very useful technique for the analysis of biological materials, such as DNA, protein and lipids, to identify elements from fingerprints, body fluids, hair, fibers, in order to reveal the identity of the person who left them.
This technique has become an essential tool for researchers and also for other medical purposes, such as the diagnosis of genetic diseases, and its use is becoming increasingly important in the field of forensics.
What is the use of electrophoresis analysis in the forensic field
Electrophoresis consists of a series of procedures that allow the molecules in a sample to be separated by the use of an electric current. This current acts on the solution as they move through a matrix, such as a polyacrylamide gel, which allows the components of the sample to be followed in real time.
The molecules are separated according to their size and electrical charge, thus allowing to extract information on the molecular composition of the sample; therefore, electrophoresis in forensics requires comparison of contrasted samples.
Which are the regulatory bodies to perform a forensic test from a dna sample
The sample from the unknown subject is compared with a reference sample, such as a DNA sample taken during a medical examination or DNA sequencing to identify a person’s genetic pattern.
The technique of electrophoresis for forensic evidence is highly regulated by regulatory bodies such as the FBI and various international agencies; the quality of work is tightly controlled to ensure accurate and reliable results.
The results of electrophoresis allow identification of suspects in criminal cases
Quality control procedures are developed in order to provide safe and fair results and ensure the protection of the rights of individuals.
The results obtained by electrophoresis are used as decisive evidence for the identification of subjects in criminal cases, as well as to identify the relationship between the material found at crime scenes and the suspect.
The help of this technique in speeding up investigative processes, reducing waiting times and addressing court cases is incalculable
To ensure accurate results, investigators should strictly follow established protocols for collecting, preparing, and evaluating appropriate materials in each case; care should also be taken to avoid any possible contamination of samples during the analysis process.
In conclusion, electrophoresis for forensic evidence is an important tool for solving criminal cases; the information obtained can be fundamental for the discovery of the truth and makes it an indispensable tool for modern forensic practice.
