Colocalization of phospho-Ser40-TH (P-Ser 40 TH) or phospho-Ser19-TH (P-Ser 19 TH) with proteasome in PC12 cells.

<p>Cells were incubated with either rabbit phospho-Ser40-TH plus mouse proteasome antibodies (upper panel) or rabbit phospho-Ser19-TH plus mouse proteasome antibodies (lower panel) followed by incubation with an anti-rabbit antibody coupled to Alexa 488 and anti-mouse coupled to AlexaFluor 594. See text for details. Scale bar = 5 μm. Three separate cell culture preparations were performed and 10 different images were taken and analyzed for each experiment. One representative image is presented.
