Cold is Gold for COVID-19 Scientists

Whether they were hospitalized at Michigan Medicine, U-M’s academic medical centre, or volunteered to have blood drawn or their nose swabbed by a U-M team after they recovered at home, all patients have helped create a vast frozen COVID-19 library.

It’s called the COVID-19 Biorepository. And ever since it launched in the spring of 2020, it’s been a trove of discovery for U-M researchers. The COVID-19 Biorepository includes 23,365 samples stored at -112F.

The ultra-cold temperatures help keep the samples intact, preserving the fragile genetic material, proteins, immune-response molecules and cellular signals that can reveal how the virus wreaks havoc in the body.
