Functional Characterization of N-Terminally GFP-Tagged GLP-1 Receptor

Figure 3

Localization of the GFP-GLP-1 receptor. CHO cells expressing GFP-GLP-1 receptor are viewed under argon-ion laser light source (488 nm) and helium-neon laser light source (543 nm) 24-hour posttransfection. Most of the protein is found outside of the nucleolus, in internal membranes (GFP, green dye), but very small amount in plasma membrane (FM4-64, red dye). Imaging is performed 24–48 hours posttransfection.
