[Corrigendum] Distinct expression of C4.4A in colorectal cancer detected by different antibodies

Following the publication of this article, an interested reader drew to our attention an anomaly associated with the presen-tation of the Fig. 2D; specifically, there appeared to have been a duplication of the same β-actin control band for the G4.4A GPI-M and the Absorbed Ab (antibody) experiments. After having re-examined our original data, we realize that the same β-actin control bands were inadvertently selected for the data shown in Fig. 2D, and this escaped out attention at the time. Our investigation of the data has also confirmed that the β-actin bands in the lower panels were produced from simultaneously performed blots using different gels or lanes with the same HCT116 cell lysates. A corrected version of Fig. 2, containing alternative data obtained from an experiment performed in duplicate, is showin below. The error with the selection of the control data did not affect the results in this study. We sincerely apologize for this mistake, and thank the reader of our article who drew this matter to our attention. Furthermore, we regret any inconvenience this mistake has caused.
