COVID-19 Research at SLAC

Here’s a look at what we’re doing to make a difference in the global fight against COVID-19.

To stop the COVID-19 pandemic, scientists need to learn a lot more about how the virus that causes the disease, SARS-CoV-2, breaks into cells and turns them into virus assembly lines that spread infection. They also need to identify its weaknesses – places where it can be blocked or attacked. This information is critical for designing vaccines to prevent infection and drugs to treat it.

SLAC joins the global fight against COVID-19

SLAC is uniquely equipped to do this work; in fact, we’ve been doing it for decades. At our large-scale facilities, which are open to scientists from all over the world, powerful beams of X-rays and electrons probe the structures and functions of proteins and other molecular machines that make all living things tick, including our bodies and the microbes that make us sick.

Among other things, these studies can reveal whether a potential drug molecule fits snugly enough into a pocket on the virus to keep it from functioning, and how specific parts of the virus interact with immune system cells that are supposed to protect us.

Our researchers are leading the development of global standards to make testing for coronavirus virus, and for the antibodies the body makes in response to infection, more reliable.

They’re also participating in Department of Energy working groups that coordinate a wide range of coronavirus research, from building low-cost emergency ventilators to finding the best ways to decontaminate face masks.

Our collaborations with Stanford University, our fellow national labs and other partners, from research institutions to industry, help move these efforts forward.

Below are some examples of this ongoing work.

Our Tools and techniques

How we study the virus

Knowing how the coronavirus is put together and how it operates at an atomic and molecular level is crucial for designing vaccines to prevent infection and drugs to treat it. SLAC uses X-rays and electrons to explore the virus’s atomic structure and understand how it infects and hijacks our cells.

 

X-ray crystallography

At SLAC’s synchrotron X-ray light source, SSRL, and at its X-ray laser, LCLS, researchers shoot powerful X-ray beams at crystallized viral proteins. By analyzing the pattern of X-rays that bounce off, scientists determine the protein’s atomic structure and how that structure changes as the protein binds to other molecules, such as potential drug candidates or components of the immune system.

Cryogenic Electron Microscopy
(Cryo-EM)

In SLAC’s cryo-EM facilities, scientists flash-freeze bits of a virus in place, then fire electrons at them to look at their atomic structures and how those structures bend and twist. They can even look at an entire frozen virus. These incredibly detailed snapshots help reveal how viruses infect cells and what they do once inside.

SLAC in times of COVID: Behind the scenes.

On March 16, 2020, the majority of our SLAC staff began working from home to follow the Bay Area counties' shelter-in-place orders. Some workers remained and others eventually returned to the lab to support COVID-19 related research conducted at our scientific facilities or resume construction on major projects. This album features a behind-the-scenes look at the lab during the pandemic. Photos will be added on an ongoing basis, so please check back for the latest.
