Fig. 5From: Imaging the rapid yet transient accumulation of regulatory lipids, lipid kinases, and protein kinases during membrane fusion, at sites of exocytosis of MMP-9 in MCF-7 cellsAverage fluorescence intensity changes (dark line; background-subtracted and normalized) associated with the red fluorescent-labeled lipid kinase isoforms, including: a PIP5KA, N = 23; and b PIP5KG, N = 11 and the SE (gray) for all traces. Dashed vertical line corresponds to the fusion event (0 s) of MMP9-GFP in the green channel, which was time-aligned to the red channelBack to article page
