MOESM1 of Characterization of lysosomal proteins Progranulin and Prosaposin and their interactions in Alzheimer’s disease and aged brains: increased levels correlate with neuropathology

Additional file 1 Figure S1. (A-B). PGRN peptide absorption of goat anti-PGRN antibody (AF2420). Low magnification images demonstrating absence of immunoreactive structures in MTG (AD case) reacted with PGRN antibody preabsorbed with PGRN peptide (A)(+PGRN peptide) and demonstration of significant immunoreactivity in parallel section from same case reacted with non-peptide antibody (B)(−PGRN peptide). Scale bars represent 200 μm. (C-D). PSAP peptide absorption of rabbit anti-PSAP antibody (AF8470). Low magnification images demonstrating absence of immunoreactive structures in MTG (AD case) reacted with PSAP antibody preabsorbed with PSAP peptide (C)(+PSAP peptide) and demonstration of significant immunoreactivity in parallel section from same case reacted with non-peptide antibody (D)(−PSAP peptide). Scale bars represent 200 μm.
