Photostability of a cysteine mutant of StayGold targeted to the ER lumen. HeLa cells expressing er-(n2)oxStayGold(c4) or er-oxGFP were subjected to continuous live imaging. Comparison was made side by side. Scale bars, 10 μm. a, WF (arc-lamp) illumination with an irradiance value of 0.21 W cm−2. b, Spinning disk confocal illumination with ...
