The primary goal of this study was to develop a method to study the N-glycosylation of IgG from swine in order to detect epitopes containing N-glycolylneuraminic acid (Neu5Gc) and/or terminal galactose residues linked in α1-3 susceptible to cause xenograft-related problems. Samples of immunoglobulin were isolated from porcine serum using protein-A affinity(More)
The aim of this report is to emphasize the role, usefulness and power of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) in the analysis of glycoforms of antibodies (Abs) through their proteolytic glycopeptides. Abs are complex biomolecules in which glycans hold determinant properties and thus need to be(More)
