Abstract
- In historical cases, missing persons' identification, mass disasters, and ancient DNA investigations, bone samples are often the only and always the best biological materials available for DNA typing. There are many protocols for the extraction of DNA from bone samples. In our experiment, we tested three DNA extraction protocols: Ethanol down method, Microcon(R) YM-100 and DNA IQ(TM) system. We have found that ethanol down method is not suitable to extract DNA from bone samples and Microcon(R) YM-100 is the best among these three mothods. DNA IQ(TM) System did not show better result but needed less time and labor than Microcon(R) YM-100. So, we expect using DNA IQ(TM) System is useful in case of bone samples which are not severely contaminated .
