<i>P. pastoris</i>-derived recombinant proteins utilized in the study

<p>More details regarding the proteins, including schematics of glycosylation sites and representative gels, can be found in reference <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0001009#pone.0001009-Lam1" target="_blank">[18]</a>.</p>*<p>Two asparagine (N) residues in the OVA portion were mutagenized to two glutamine (Q) residues, thus preventing formation of N-linked glycans.</p>**<p><i>P. pastoris</i>-produced ppOVAST was subjected to chemical deglycosylation using TFMS.
