Application of PEPCy tags for single molecule and time-lapse microscopy of cell surface proteins. A. Micrographs of HEK cells expressing PEPCy3 or HT on their surfaces labeled with Cy3, and B. cells expressing PEPCy5 or HT on their surfaces labeled using Cy5. The colormap is inverted to clearly show single molecules against the white background. Normalized probability distributions of integrated single molecule signal above the background are shown adjacent to each image. (N = 1200-2000 single molecules per sample for A and B). Scale bar is 5 µ m. C . Probability distributions of the background counts from single PEPCy3 or HT-Cy3 molecules expressed on HEK cell surfaces and imaged via TIRF microscopy (N = 998 for PEP and 1020 for HT) D . Probability distributions of the background counts from single PEPCy5 or HT-Cy5 molecules expressed on HEK cell surfaces and imaged via TIRF microscopy (N = 1133 for PEP and 784 for HT). E . Wash-free extended tracking of single PEPCy5-B2AR-Ala molecules on HEK cell surface. The first image of each acquisition is shown. The black vertical lines represent the instance and duration of the illumination turned off. The graph below shows the number of localizations per frame as a function of time in this experiment. F . Time-lapse confocal microscopy of HeLa cells expressing B2AR-Ala-PEPCy5 labeled using Cy5. Numbers on the left of each image denote the time in minutes. Images were acquired every 30 s for 30 mins. G . Normalized frequency distributions (bars) and cumulative probability (dashed lines) of median speed per trajectory for PEPCy3-B2AR and PEPCy5-B2AR-Ala molecules (trajectory N = 42906 for PEPCy3 and N = 25253 for PEPCy5) H . Normalized frequency distributions (bars) and cumulative probability (dashed lines) of jumps in a 50 ms duration for PEPCy3-B2AR and PEPCy5-B2AR-Ala molecules.
