||Researchers present an assay called “bleach-chase” for measuring protein half-lives that does not require translation inhibitors, antibodies, or radioactive labeling. In the bleach-chase method, the fluorophore of the tagged protein is bleached using a brief pulse of light, irreversibly rendering it nonfluorescent. Half life obtained using the equation on p.765 under fig.1, half life=ln(2)/alpha taking average alpha as 0.1 (p.766 note under fig.2D)
||Note, in p.765 middle column bottom paragraph a mean value of 9 hours is given: "[Researchers] observed a broad protein half-life distribution ranging between 45 min to 22.5 hours, with mean 9.0±4.6 hours (Fig. 2D and table S4)." H1299 human non–small cell lung cancer cell line.
