Fig. 3. The utility of chimeric VLRs for galactose-3-sulfate detection as demonstrated by western blotting, TLC-overlay, ELISA, and flow cytometry.

Fig. 3

a O6-mFc detects galactose-3-sulfate on the N-glycans of bovine thyroglobulin and O-glycans on human mucins. b O6-mFc bound to sulfatide and not porcine gangliosides in TLC-overlay. c Validation of b and c by ELISA, using O6-mFc at 4 concentrations. n = 2, each black triangle represents one data point, error bars = ±1 standard deviation. d Dose-dependent binding is observed by flow cytometry of Pro-5 CHO cells and not Lec8 mutants. Lec8GT CHO cells are positive; however, addition of α1-3 linked fucose to the LDN motif abrogates binding in Lec8GTFT cells.
