Western blot analysis of Kv1.4 subunit expression in hippocampus and cerebral cortex.

<p>Representative immunoblot of (<b>a</b>) hippocampus and (<b>b</b>) cerebral cortex enriched membrane proteins (50 µg/lane) from (Ctr), Aβ_25–35, Aβ_25–35+SP and SP treated rats. Protein markers are shown at right (in kDa). The immunoreactive signals at 97 and 110 kDa were quantified and normalized against β-actin and expressed as a percentage of the control (Ctr). Data represent mean (±SEM) from 5 independent experiments. Statistically significant differences were calculated by one-way analysis of variance (ANOVA) for repeated measures followed by Tukey's test for multiple comparisons (**p<0.01 versus Ctr value; #p<0.05 versus Aβ_25–35 treatment).
