Figure 4

Labeling efficiency and cytotoxicity of 6-Az-Fuc. (A) Neuro2A cells were treated with DMSO, 100 μM peracetylated 6-Alk-Fuc, 7-Alk-Fuc or 6-Az-Fuc. Incorporated Fuc analogs in the cell lysates were biotinylated by click chemistry, and the labeled glycans on proteins were detected by blotting with HRP-streptavidin. For labeling, the same concentrations of biotin-azide (lane 1–3) and biotin-alkyne (lane 4 and 5) were used. (B) Growth of HEK293 and Neuro2A cells was examined after addition of DMSO or peracetylated 6-Az-Fuc at Day 0 (n = 3). All graphs show means ± SD.
