Representative bands of protein from different cellular fractions of frontal cortex and hippocampus. A) Representative bands of post-synaptic density-95 (PSD-95) and syntaxin proteins in homogenate (H), light membrane (P3), and synaptosomal membrane (LP1) fractions from caudal cortex. B, C) Representative bands of NR2B and NR1 subunit proteins of the NMDA receptor and GAPDH protein from homogenate, light membrane fraction and synaptosomal membrane fraction for frontal cortex (B) and hippocampus (C) from 4-, 11- and 26-month-old mice. Note: The scanned bands were in color when analyzed. The images were converted to grayscale for publication purposes. For each protein and fraction shown, the images of bands representing the three different age groups were all obtained from the same gel and were adjusted for brightness and contrast as a group.
