Erratum to: Real-time ALT and LDH activities determined in viable precision-cut mouse liver slices using hyperpolarized [1- ¹³ C]pyruvate-Implications for studies on biopsied liver tissues (NMR in Biomedicine, (2019), 32, 2, (e4043), 10.1002/nbm.4043)

In the paper by Lev-Cohain et al,¹ the calculated activities of LDH and ALT reported should have been 4-fold lower. This erratum corrects the text and supporting information errors that result from this mistake. These corrections do not affect any other result in the paper or any of the paper's conclusions. The 2^nd sentence in the last paragraph of the Results should read as: On average, LDH activity and ALT activity were found to range between 0.29 and 1.04 nmole/s/g wet weight and between 0.65 and 2.42 nmole/s/g wet weight, respectively, and both correlated to the ATP level of the sample (Supporting Sections S8 and S9). The 1^st sentence of the 3^rd paragraph in the discussion should read as: [1-¹³C]lactate production in liver slices was found here to range between 0.29 and 1.04 nmole/s/g wet weight. The 1^st sentence of the 4^th paragraph in the discussion should read as: The [1-¹³C]alanine production rate determined here was 0.65 to 2.42 nmole/s/g wet weight. The y-axes of Figure S8 and Figure S9 (upper two right panels) are corrected below. Corrected Figure S8. (Figure presented.) Corrected Figure S9. (Figure presented.).
