Western blot of Aβ42 from extracellular enriched cellular fractions, respective to NNC 26-9100 and phosphoramidon (Phos) treatment. Soluble oligomeric Aβ42 forms identified at 56, 50, 40, 25, and 12 kDa. Protein evaluated with optical densities normalized to respective vehicles (n = 4 5/group). ** P < 0.01 compared to respective vehicle; † P < 0.05 compared to NNC 26-9100 alone, two way ANOVA, values are mean ± S.E.M. ¥ indicates delineated split of the 25 kDa band with NNC 26-9100 treatment, which was reversed with phosphoramidon treatment (1 or 10 mM). Representative blots shown to right of bar graph.
