| Method | 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 simple equation on p.765 under fig.1, half time=ln(2)/alpha taking average alpha as 0.1 (p.766 note under fig.2D) |
