doi: 10.1371/journal.pone.0311107
Figure Lengend Snippet: ( A ) Confocal images of a HeLa cell expressing VDAC1-TC, mitoCFP, and mCh-ER3; the cell was labeled with 1 μM FlAsH for 15 min and washed with 100 μM Bal for 10 min. The left image shows an overview of the cell, and the dashed squares are magnified on the right side. Yellow arrows point to positions of VDAC1-clusters at ER-mitochondria contact sites. Dashed lines represent the line scan graphs on the right and show the relative fluorescence intensity of VDAC1-TC (green), mitoCFP (blue), and mCh-ER3 (magenta) along the length of the line. ( B ) The graph shows the percentage of VDAC1-clusters that colocalize with the ER (n = 8). ( C ) Structured illumination microscopy images of a HeLa cell expressing VDAC1-TC with mCh-Sec61β; cell was labeled with 1 μM FlAsH for 15 min and washed with 100 μM BAL for 10 min. Dashed line represent the line scan graph on the right and show the relative fluorescence intensity of VDAC1-TC (green) and mCh-Sec61β (magenta) along the length of the line. Arrow point to the position of a VDAC1-cluster at ER contact sites.
Article Snippet: HeLa S3 cells, a clonal derivative of the parent HeLa cell line, were obtained from ATCC and authenticated with STR analysis.
