Fig. 6From: Direct imaging of glycans in Arabidopsis roots via click labeling of metabolically incorporated azido-monosaccharidesOptical sections of 4 day old Arabidopsis seedling roots incubated for 48 h with 2.5 μM (b), 10 μM (c), 25 μM (d), and 100 μM (e) Ac4GalNAz, followed by labeling through a copper-catalyzed click reaction with Alexa Fluor® 488 alkyne. As a control, seedlings were treated with 0.01 % DMSO (a). Scale bars = 50 μm (see Additional file 14 for high resolution)Back to article page
