Quantification of lengths and angles in the ER network. (a) Schematic with definitions of lengths and angles used in this analysis. Tubule contour length, \(L\), is shown as a red dashed line, the arclength, \(s\), is shown as a black dashed arrow and the end-to-end distance, \(R\), is shown as a dark blue solid arrow. Junctions between two and four tubules are highlighted with orange and yellow circles respectively. (b) Histogram of Vero (blue) and MRC5 (red) ER tubule lengths, measured in fixed Vero cells and stills of live MRC5 cells. (c) Angles measured in the ER network of MRC5 cells, separated by the junction co-ordination number (shown in key). (d) Angles within the ER network of Vero cells, separated by junction co-ordination number (shown in key).
