Scientists get a clearer and more accurate image of proteins

Proteins are among the most significant and diverse biomolecules found in living organisms. These strings of amino acids, which take on complex 3-dimensional structures, are required for tissue growth and maintenance, the activation of thousands of biochemical events, and the immune system’s defense against invaders.

High-speed cell sorter rapidly isolates and quantifies cells with complex cellular phenotypes

Isolating individual cells with complex phenotypes – which is key to understanding how these cells function, including to inform disease – is a technological challenge. Now, overcoming this hurdle, researchers present a high-speed cell sorter that uses fluorescence imaging to enable genome-scale studies of complex phenotypes.
