Procainamide Cleanup Plate

For removal of excess procainamide label after labeling of glycans. This clean-up plate is used where excess procainamide interferes with subsequent sample analysis.

Procainamide Labeling Kit

Procainamide labelling permits glycan identification by either mass spectrometry or UHPLC. Because of its improved ionisation efficiency compared to 2AB labelling, it can permit identification of minor glycans (1% relative peak area) by ESI-MS. This LudgerTag kit, along with a post-labelling clean up plate for the samples (catalog# LC-PROC-96), has been validated in house at Ludger. Typical CVs for triplicate analyses were 5%

Permethylation Kit

This kit is used for the permethylation of glycans. Permethylation stabilizes sialic acids for MALDI mass spectrometry analysis, and aids linkage analysis studies (MALDI-MS, ESI-MS).

- Improves and enhances ionization efficiency of glycans on mass spec
- Increased glycan hydrophobicity enables LC-MS analysis
- Relative and absolute quantitation can be performed
- Stabilizes the sialic acid moieties
- Easier determination of branching and glycosidic linkage positions
- Enables detection of both neutral and acidic glycans in positive ion mode
