LudgerTag Procainamide Glycan Labeling Kit

Procainamide labeling permits glycan identification by either mass spectrometry or (U)HPLC, and because of its improved ionisation efficiency
compared to 2AB labeling it can permit identification of minor glycans (<1% relative peak area) by ESI-MS.

Ludger's procainamide labelling system is suitable for N-glycans, O-glycans, GSL-glycans, heparin or any sugar with a reducing terminus.

Our labelling kit uses the same reductive animation labelling method that has been used for 2AB & 2AA. We have also incorporated 2PB as a
reductant in place of sodium cyanoborohydride which makes the method safer to use. Once labelled the glycans are suitable for incubation
with exoglycosidases.

We also offer a clean up system for use after labelling and a range of procainamide labeled glycan standards
(including an N-glycan library and glucose homopolymer ladder).

The presentation below relates to our LT-KPROC-VP24 kit. Results for LT-KPROC-24 are directly comparable.
