In the article “Endopin Serpin Protease Inhibitors Localize with Neuropeptides in Secretory Vesicles and Neuroendocrine Tissues” [Neuroendocrinology. 2009;89(2):210–16. https://doi.org/10.1159/000162916] by Hwang et al., the authors found that an incorrect label was present for lanes E2 and ACT in Figure 1a. The authors stated that this does not impact the figure’s conclusion that the anti-E1 antibody specifically detects E1, rather than ACT or E2.

The corrected Figure 1 is shown here.
