Labeling profiles of cel-p in living primary neurons. A Concentration-dependent (0–1.6 μM) labeling profiles of cel-p in normal and OGD injury primary neurons. B Competitive labeling profiles of cel-p (0.8 μM) in normal and OGD injury primary neurons in the presence of cel (2 × , 4 × , 6 × , 8 ×). C Cel-p mainly localized in the cell cytoplasm within 2 h and gradually entered the cell nucleus after 2 h. FL, in-gel fluorescence scanning; CBB, coomassie brilliant blue gel
