<i>Chop</i> gene and protein expressions in the hippocampus isolated from wild type and <i>chop</i> knockout mice.

<p><i>Chop</i> genome typing and protein expression in the hippocampus isolated from C57BL/6J mice and <i>chop</i>−/− mice 1 day after intracerebroventricular injection of tunicamycin (0.1 and 1 mg/ml) were detected by the PCR (A) and Western blotting (B), respectively. Representative images of three independent experiments are shown.
