Quantification of HPG incorporation into newly synthesized polypeptides (HPG-Alexa488) as function of recovery time following 1-h Na3AsO4treatment of cells (described in A). Recovery from stress was by replacement of media without Na3AsO4but with RK-33 or DMSO and HPG. Mean, SEM,n= 3. Lines are drawn to guide the eye. Boxplots depict the 25th75thpercentiles with indicated median and whiskers for minimum and maximum values and outliers depicted in gray. *p< 0.05,**p< 0.01,***p< 0.001.
