ABSTRACT
OBJECTIVE@#To compare the effectiveness of two methods of DNA extraction from different colour costal cartilages in STR genotyping.@*METHODS@#DNA fragments were extracted from costal cartilages of different colour of 30 corrupt corpses using Chelex-100 and Phenol-Chloroform methods. STR loci were analyzed by ABI 3100 genetic analyzer after PCR amplification by using Profiler Plus kit.@*RESULTS@#STR loci were completely detected in all 30 samlpes of costal cartilages when using Phenol-Chloroform DNA extraction methods. While using Chelex-100 methods, all STR loci were identified in 22 cases (11 white, 8 light-yellow and 3 yellow cases). Partial STR loci were detected in 7 cases (3 yellow and 4 yellow-brown cases) and none in 1 brown-black cases.@*CONCLUSION@#Suitable DNA extracion methods will be chosen depends on the colour of costal cartilage. Phenol-Chloroform methods is more effective in STR genotyping especially in dark colour costal cartilage cases.
