Mayo Clinic’s state-of-the-art biorepository stores 2.5 million samples of blood, tissue, urine and other DNA specimens. It’s a “one-stop shop” for clinical investigators, according to co-director Dr. Stephen Thibodeau.

Journalists toured the biobank as part of a National Press Foundation training program on precision medicine, which is health care tailored to each individual based on their personal genomics.
