1. METHODS RELATED TO CELL SURFACE GLYCOSYLATION 2010-8-5

Abstract:
The present disclosure provides methods for assessing the glycosylation of a target glycoprotein produced by a cell through analysis of cell-surface glycans on the cell. The present disclosure therefore teaches that glycosylation of cell surface proteins can serve as a proxy for glycosylation of other proteins.

2. GALACTOSE-ALPHA-1, 3-GALACTOSE-CONTAINING N-GLYCANS IN GLYCOPROTEIN PRODUCTS DERIVED FROM CHO CELLS 2010-7-29

Abstract:
The present invention provides methods for evaluating a Chinese Hamster Ovary (CHO) cell population by measuring glycans containing terminal galactose-alpha-1-3-galactose residues produced by said cells, wherein the CHO cells have not been genetically engineered to express an alpha-galactosyl transferase coding sequence.

3. COMPARATIVE ANALYSIS OF PROTEIN CONFORMATIONS BY USING 2D NOESY NMR SPECTRA 2010-7-29

Abstract:
The present disclosure provides a method for determining the relative conformations of a protein provided in different protein preparations, comprising steps of: (i) obtaining a first 2D NOESY NMR spectrum of a first protein preparation; (ii) obtaining a second 2D NOESY NMR spectrum of a second protein preparation; and (iii); determining whether a protein has a different conformation in the first and second protein preparations by comparing one or more cross-peaks in the first 2D NOESY NMR spectrum with one or more corresponding cross-peaks in the second 2D NOESY NMR spectrum.

4. NON-ANTICOAGULANT POLYSACCHARIDE COMPOSITIONS 2010-7-21

Abstract:
Polysaccharide preparations lacking substantial anticoagulant activity are provided herein. Methods of making and using such preparations are provided.

5. METHODS RELATED TO MODIFIED GLYCANS 2010-6-24

Abstract:
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.

6. CHARACTERIZATION OF O-LINKED GLYCANS 2010-6-24

Abstract:
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.

7. MULTI-DIMENSIONAL CHROMATOGRAPHIC METHODS FOR SEPARATING N-GLYCANS 2010-6-17

Abstract:
A multi-dimensional chromatographic method for the separation of N-glycans. The method comprises providing a glycan preparation that includes at least one negatively charged N-glycan. The glycan preparation is then separated by anion-exchange chromatography and at least one secondary chromatographic technique.

8. PROTEOLYTIC RELEASE OF GLYCANS 2010-6-17

Abstract:
The present disclosure provides strategies for analyzing protein-linked glycans, and particularly for analyzing glycans on cell surface glycoproteins.
