This is the second episode of our four part series focused on the CZ Biohub in San Francisco where scientists are working to cure, prevent, or manage disease by the end of the century. In this episode, we meet Quantitative Cell Science group leader Manu Leonetti. Manu and his team are using "genetic glowsticks" to map all 20,000 proteins in a single human cell. Their flagship project – OpenCell – is a library of fluorescently engineered cell lines to define the locations and interactions of human proteins within our cells.
