Serum mannosidase trims protein-conjugated oligomannose mimetic in vitro. Shown is PGT128 binding to the BSA-conjugated (a) or the CRM197-conjugated glycoside (b) (5 µg/ml) after in situ overnight incubation of glycoconjugate-coated ELISA plates with buffer, mammalian serum, serum supplemented with kifunensine (Kif) or serum supplemented with EDTA. All experiments for a given serum were performed on a single assay plate to avoid potential plate-to-plate variability. Shown are representative results from two independent experiments.
