Published customer image: . Sheep anti Human TGN46 antibody ( AHP500 ) used for the identification of the trans golgi network in MD-MB-231 cells by immunofluorescence. Image caption: . APP redistributes from endosomes to the TGN upon overexpression of μ4-F255A-HA. MD-MB-231 cells were cotransfected with a plasmid encoding either of the indicated HA-epitope-tagged variants of u4, and with a plasmid encoding APP-GFP carrying the double mutation F615P/D664A. After 24-h cells were fixed, permeabilized, stained for EEA1 and TGN46, and examined by fluorescence microscopy. Merging green, red, and blue channels generated the fourth image on each row; yellow indicates overlapping localization of the green and red channels, cyan indicates overlapping localization of the green and blue channels, magenta indicates overlapping localization of the red and blue channels, and white indicates overlapping localization of the red, green, and blue channels.
