[Specialized software product for comparative analysis of multicomponent DNA fingerprints].

"GelAnalyzer" software, which is used to identify and correctly compare DNA fingerprints consisting of a large number of discrete bands, has been developed by the project to study the quantitative changes in DNA polymorphism patterns in animals and humans exposed to gamma radiation. The actual capabilities of this program are much broader and include the possibility to analyze the images of any multicomponent gels containing fragments of DNA, RNA, and proteins. This software product runs on Windows. "GelAnalyzer" allows one to analyze gel images obtained by a scanner, camera, or digital camera and ensures the visual control of the identification and comparative analysis of bands; it also makes it possible to take into account the bands that are poorly identified automatically and exclude the artifacts (incidental marks) on images. The operation of "GelAnalyzer" software is based on the determination of the values of normalized coordinates of bands with allowance for the relative electrophoretic mobility (Rf) of PCR products and comparison of their spectra (set of bands in gel lanes) to reveal the similarities or differences in their components with subsequent statistical data processing and display the results of the analysis.
