Genetic results from bone samples often yield low quantities of DNA and poor quality of genetic data. Proteinase K is a proteinase that is commonly used in DNA extraction methods, however the target proteins of Proteinase K do not closely align with the makeup of bone. Collagenase Type 2 is a protease that is more specific to the breakdown of collagen, which bone is comprised of. This study looked at the potential effects of Collagenase Type 2 digestion on bone samples compared to the effects of Proteinase K on quantity and quality of genetic typing. This study also incorporates the EZ1 Advanced XL purification platform and the AmpFLSTR Globalfiler Amplification Kit.
