FIGURE 4.
GCPII levels in young vs. aged rat frontal cortex. (A) Rat frontal cortex tissue (18 μg of protein loaded per well) was immunoblotted for GCPII and GAPDH. Each lane represents a single animal and is labeled either young (gray Y) or aged (red A). (B) Quantification of GCPII normalized by GAPDH grouped by age. Young animals (n = 10) and aged animals (n = 10) are compared via an independent t-test (***p = 0.0004). SEM is plotted for each group.
