Fig. 5From: 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 24 h with 25 μM acetylated Ac4GlcNAz (a) or non-acetylated GlcNAz (b), followed by labeling through a copper-catalyzed click reaction with Alexa Fluor® 488 alkyne. Early incorporation with GlcNAz was observed with seedlings incubated for 2 h with 25 μM GlcNAz (c). Scale bars = 50 μm (see Additional file 14 for high resolution)Back to article page
