    摘要: Among other things, the present disclosure provides methods for enriching, identifying, and/or quantifying unusually modified glycans (e.g., phosphorylated glycans, sulfated glycans, and/or multi-acetylated glycans). In many embodiments, methods comprise providing a glycan preparation from which sialic acids have been released; subjecting the sialidase-treated glycan preparation to a separation technique that separates glycans based on charge-to-mass ratio; and quantifying the charged products using at least one quantification standard.

    摘要: The present disclosure provides methods for analyzing structure and/or composition of glycoproteins and glycans of glycoproteins. Such methods can include subjecting a glycoprotein preparation to a condition that removes at least one O-linked glycan from the glycoprotein. Such methods can include subjecting a glycoprotein preparation to a condition that releases an N-glycan from the glycoprotein, e.g., prior to subjecting the glycoprotein to a condition that releases an O-glycan from the glycoprotein.

    摘要: Methods of analyzing glatiramer acetate (GA) or a polymeric precursor thereof are provided. The methods can include determining a level of one or more diethylamide-modified amino acids in a sample comprising GA or a polymeric precursor thereof, and selecting at least a portion of the sample based on the assessment of the one or more diethylamide-modified amino acids in the sample.
