Application of Capillary Electrophoresis in Forensic Molecular Genetic Investigation
Grafnetterová, Anna ; Doubková, Klára (advisor) ; Coufalová, Pavla (referee)
5 Abstract The capillary electrophoresis (CE) is an analytical method based on the principle of the traditional plate electrophoresis. Modern ways of fluorescence marking and the detection result in the higher reliability of analyses as well as in more precise results. The utilization of this method is wide within a lot of science fields. In special cases this method can even replace methods used so far, i.e. HPLC. The CE is mainly used in the forensic investigation in particular for person identification based on the DNA analysis of the even minimal sample amount. The STR analysis is an example of such examination. It uses short tandem repeats with high variability within the population. Commercial companies e.g. Promega Corporation, Applied Biosystems etc., develop corresponding instrumentation, software and kits which are important for receiving correct data. As a final result it is obtained DNA profile evaluated by comparison of samples from the "crime scene" with the reference samples. Besides the using in the human domain the DNA profiles are often used in the veterinary practice, in animal (cats, dogs, horses, cattle etc.) raising or breeding, for improving the particular characteristics. Key words: capillary electrophoresis fluorescent labeling STR STR analysis DNA profil
