A number of antibodies and antibody fusions are currently used as therapeutic agents. A conserved N-glycan at Asn297 of the Fc region of IgG is critical for functional activity. PNGase F is the most effective enzymatic method for removing almost all N-linked oligosaccharides from glycoproteins. Rapid rPNGase F is a recombinant amidase, which cleaves between the innermost GlcNAc and asparagine residues of high mannose, hybrid, and complex oligosaccharides.
Application：
-
Characterizing whether the protein is glycosylated
-
Characterizing the N-glycan chain structure of glycoproteins
-
Determining the location of glycosylation on the protein
the key Featuers ：
-
Can be used for glycoproteins under native or denaturing conditions
-
Rapid cleavage：10min cut-off N-Glycan chain of mAb
-
≥ 99.5% purity，as determined by UPLC/ESI-MS
-
