CreaTag™ V-TAG Glycan Release and labelling kit [For Glycan Labeling] (CAT#: CB-P295-K) Datasheet

Product Type
The kit contains the reagents required to release PNGase F of aminoglycans, and then a dedicated solid phase extraction (SPE) column for fluorophore labeling and purification of labeled glycans.
Number of Samples: 30 separate analytical samples per kit.
Amount of Sample: As a guideline up to 100 µg of glycoprotein per sample.
Suitable Samples: Glycoproteins and glycopeptides containing N-linked glycans.
Release of aminoglycans from glycoproteins, subsequent fluorophore labeling and clean up
