Facility dedicated to study of degraded and low DNA yield samples, such as environmental DNA, historical DNA, or ancient DNA. Offers positive pressure lab spaces that follow strict decontamination procedures to prevent human, bacterial, and fungal contamination. It is physically isolated from tissue samples or polymerase chain reaction (PCR) products to avoid contamination from samples with higher DNA concentration and quality. The space has dedicated equipment necessary for DNA extraction and PCR-free sample preparation.
