Figure 5From: A Modified Coupled Enzyme Method for O-linked GlcNAc Transferase Activity Assay Linear relationship between C-654 amount and OD 570 nm . Assays were performed under varying C-654 amount from 1 to 50 μg per well in the standard reaction mixture as indicated in "Materials and Methods." The error bars indicate the range of standard deviation of the experimental data.Back to article page
