Flow Cytometry Channels Photonics to Advance Immunology
The COVID-19 pandemic has put the field of immunology under an international spotlight. Researchers in the field have been rigorously studying our immune system’s response to the SARS-CoV-2 virus to understand how we combat infection. Advancements in immunological detection have relied on one instrument in particular: the flow cytometer. “Flow cytometry is important to our understanding of all infectious diseases,” said William Telford, who heads one of the National Cancer Institute’s...
