Rate of glycoprotein immobilization and PNGase F release of N-glycans. (a) Fetuin was conjugated to Aminolink resin via reductive amination, whereas the unbound proteins in supernatant were measured by a BCA assay. Fetuin was quickly immobilized to the resin within 4 h; (b) N-glycans were released by PNGase F in 25 mM ammonium bicarbonate at 37 °C. The PNGase F digestion was complete within 2 h. Four measurement were made for each condition and error bar represented standard deviation.
