(A-C): Double-label immunofluorescence images using the PHF-1 antibody (red, A), BeclinCCP antibody (green, B), and the two images overlapped (C). (D-F): Double-label immunofluorescence images using BeclinCCP antibody (red, D), the early tau conformation marker, MC-1 (green, E) and the two images overlapped (F). Yellow, orange coloring represents areas where markers are overlapping, which in this case was evident (arrows, F). (G-I): Identical to (D-F) showing in this case the lack co-localization within a damaged astrocyte labeled with BeclinCCP antibody (arrowhead, I), whereas co-localization between the two antibodies was evident within an apparent tangle-bearing neuron (arrow, I). All scale bars represent 10 μm.
