Correction: Comprehensive Metabolic Tracing Reveals the Origin and Catabolism of Cysteine in Mammalian Tissues and Tumors Free

In the original version of this article (1), there were errors in the “LC/MS analysis and data processing” section of the Materials and Methods. The SeQuant ZIC-pHILIC column and SeQuant ZIC-pHILIC guard column were incorrectly stated to be 5 μmol/L instead of 5 μm. In addition, the description of the use of mobile phase A and B was incorrect and should read “0–13 min, 80% to 20% of B; 13–15 min, 20% of B; 15–20 min, 80% of B.” Finally, the capillary temperature was listed incorrectly as 30°C, whereas the correct temperature is 320°C. The errors have been corrected in the latest online HTML and PDF versions of the article. The authors regret these errors.
