Identification of O-glycosylation sites in rhPDGF-BB using LC/MS.

Abstract

<p>(A) Schematic representation of PDGF-B mutants. Monoisotopic mass of every mutant is shown. (B) Deconvoluted mass spectra of the wild-type PDGF and its mutants are presented with monoisotopic peaks; glycosylated isoforms are annotated.</p
