CST colocalizes with HSPGs. Representative confocal fluorescence images of BAE-1 cells incubated with both Alexa Fluor 488-anti-HSPGs (green signal) and Cy3-CST (red signal), showing the high levels of colocalization for CST and HSPGs (% of colocalization = %, 3 separate experiments, 6 fields/sample, about 25 cells/field).
