RESUMEN
OBJECTIVE@#For the purpose of solving a problems of DNA testing of burned bones.@*METHODS@#We present a novel strategy to obtain DNA from burned bones based on the use of cetyltrimethylammonium bromide (CTAB) lysis buffer and isoamyl alcohol-chlorophorm extraction with subsequent DNA purification using the DNA IQ System.@*RESULTS@#The methods were found to be effective in removing the PCR inhibitors from the burned bone. Then the extracted DNA was successfully genotyped by using the florescence labeling STR multiplex method.@*CONCLUSION@#The results of this research will assist forensic scientists in the identification of DNA from victims whose bodies underwent significant trauma or burning, precluding the utilization of traditional forensic DNA identification techniques.
