Polarized Microscopy Shows Protein Position
NEW YORK, April 21, 2011 — A new polarization-based technique can help deduce the orientation of specific proteins within a cell. By turning their instruments toward the nuclear pore complex — a huge cluster of proteins that serves as a gateway to a cell's nucleus — scientists at Rockefeller University have filled the gaps left by other techniques and made important discoveries about how the complex works. Although researchers have spent years studying the workings of the nuclear pore complex, much has...
