Comparative Glycopeptide Analysis for Protein Glycosylation by Liquid Chromatography and Tandem Mass Spectrometry: Variation in Glycosylation Patterns of Site-Directed Mutagenized Glycoprotein

Figure 3

Triplicate analysis for glycosylation patterns of the reference rAb sample using LC-ESI-MS/MS. Each acquired mass dataset was normalized before comparative analysis. The sugar symbols: diamond (magenta) = sialic acid, circle (yellow) = galactose, square (blue) = GlcNAc, circle (green) = mannose, triangle (magenta) = fucose.
