B. Representative images of a time course analysis of TRAPPC2 redistribution to SGs. Cells were treated The graph (B') shows quantification of TRAPPC2 localization at SGs over time as the ratio between TRAPPC2 (mean fluorescence intensity) in SG puncta and cytosolic TRAPPC2. Mean ± s.e.m. n = 50 cells per experiment, N = 3. Scale bar, 10 µm.
