Low Amount of DNA

DNA yields of approximately 70 ng/pL can be measured for bone samples, and yields of less than 2 ng/pL can be measured for soft-tissue samples.[5] We have recovered 23 ng of DNA per milligram of dried aorta tissue naturally preserved for approximately 1.5 years. Polymerase chain reaction amplification fails when the amount of available DNA is too minute.[16] Both bone and soft-tissue samples are suitable for ancient DNA analysis, but that skeletal remains should be given preference when source materials are severely degraded.
