Imaging method highlights new role for cellular ‘skeleton’ protein – Phys.org

While your skeleton helps your body to move, fine skeleton-like filaments within your cells likewise help cellular structures to move. Now, Salk researchers have developed a new imaging method that lets them monitor a small subset of these filaments, called actin.
“Actin is the most abundant protein in the cell, so when you image it, it’s all over the cell,” says Uri Manor, director of Salk’s Biophotonics Core facility and corresponding author of the paper. “Until now, it’s been really hard to …
