Immunoprecipitation and Western blot analysis detection of AGO protein. Human frontal cortex samples from 3 individual cases (a (case 3), b (case 1), and c (case 5)) and rat cortical tissue (d) were subjected to subcellular fractionation followed by immunoprecipitation (IP) with either anti-AGO (2A8, generated in mouse) or normal mouse serum (NMS). The immunoprecipitation products were analyzed by Western blotting using a rabbit anti-AGO antibody (Cell Signaling). AGO was found in all of the 2A8 immunoprecipitation subcellular fractionation samples but not in samples incubated with NMS. Incubation with NMS was not conducted on every mitochondria (pMito) and MAM samples due to the relatively low abundance of protein in these two subcellular fractions.
