Protocols: Ancient Dna: Methods And

The goal of extraction is to release DNA from the mineral matrix (bone) while removing inhibitors like humic acids.

Modern DNA from researchers or the environment is "fresher" and more intact than aDNA, making it easy for a tiny amount of modern DNA to overwhelm the ancient sample. 2. Sample Selection and Preparation Ancient DNA: Methods and Protocols

Working with aDNA is fundamentally different from modern genomics due to three primary hurdles: The goal of extraction is to release DNA

All work must be done in a dedicated "Clean Lab" with HEPA filtration, positive air pressure, and UV sterilization. Researchers wear full-body suits to prevent shedding their own DNA onto the samples. positive air pressure
