What Is the Forensic Biology and Genetics Laboratory? What Is Its Purpose?
The Forensic Biology and Genetics Laboratory at Üsküdar University is an advanced training and research facility that provides both academic and hands-on education in the analysis and identification of biological evidence collected from crime scenes.
Primary Objective: The laboratory aims to equip students with the skills required to extract, amplify, and analyze DNA from biological samples associated with forensic cases, such as blood, saliva, and hair, and to interpret analytical results in accordance with forensic reporting standards.
Academic Contribution: The laboratory contributes to the education of highly qualified forensic professionals by providing practical training in the preservation of biological evidence, contamination prevention, and the application of internationally recognized forensic genetics protocols and data analysis methods.
Laboratory Equipment and Technical Infrastructure
The laboratory is equipped with advanced instrumentation that enables molecular biology and forensic genetics analyses to be performed with a high degree of accuracy and reliability. The primary equipment includes:
Thermal Cycler (PCR System): Used to amplify specific DNA regions obtained from trace forensic samples, generating millions of copies for molecular analysis.
Genetic Analyzer: Utilized to separate PCR-amplified DNA fragments by size using capillary electrophoresis, detect fluorescent signals, and generate DNA profiles for forensic identification.
Centrifuges and Microcentrifuges: Used to separate biological fluids and cellular components through high-speed centrifugation and to perform precipitation steps during DNA extraction procedures.
Vortex Mixers and Heating Blocks: Provide homogeneous mixing of chemical reagents and maintain the stable temperatures required for enzymatic reactions during molecular analyses.
Precision Pipettes and Sterile Consumables: Enable accurate liquid transfer at the microliter level while minimizing contamination risks and ensuring the reliability of analytical results.
Research and Practical Training Areas
The laboratory supports practical courses and academic research in the interdisciplinary fields of forensic biology and molecular genetics.
Biological Evidence Isolation: Application of techniques for obtaining high-quality, analysis-ready DNA from biological materials collected from various surfaces.
DNA Profiling and Human Identification: Covers molecular preparation procedures required before Short Tandem Repeat (STR) analysis and practical applications in forensic human identification.
Biological Stain and Body Fluid Analysis: Identification and forensic classification of suspected biological stains, including blood, semen, and saliva, collected from crime scenes using biological testing methods.
Parentage (Paternity) Testing Infrastructure: Provides model applications for the molecular analysis of genetic inheritance and biological relationships between individuals.
Benefits for Students and the Professional Sector
The Forensic Biology and Genetics Laboratory enhances students' professional competencies through extensive practical training while contributing to the growing demand for qualified professionals in forensic sciences.
Professional Standards: Students gain hands-on experience in international laboratory quality management systems, biosafety procedures, sterilization protocols, and contamination control practices required in modern forensic laboratories.
Industry Preparation: Graduates who complete laboratory-based training develop practical expertise in contemporary molecular techniques used in criminalistics laboratories, forensic medicine institutions, biotechnology research and development centers, and genetic diagnostic laboratories. This experience prepares them for successful careers in the field.
