N-Glycanase-PLUS®, 400 mU [GKE-5010B]

Price:
$ 1,060.00

Description

PNGase F, peptide-N-glycosidase F, peptide-N4-(N-acetyl-β-glucosaminyl)asparagine amidase. Releases intact N-glycans by cleaving between the innermost GlcNAc and Asn.

Source:
Recombinant gene from Elizabethkingia meningosepticum, expressed in E. coli. The source organism was previously known as Chryseobacterium Chryseobacterium [Flavobacterium] meningosepticum [1].

Specificity: 
Cleaves all N-linked complex, hybrid or high mannose oligosaccharides, unless α(1-3) core fucosylated, as in plant glycans. Asparagine must be peptide-bonded at both termini. Phosphate, sulfate and sialic acid groups attached to the oligosaccharide do not affect cleavage. Endo F free. Highly concentrated, particularly useful for deglycosylation under native conditions.

R1: N & C substitution other than H
R2: may be H or the rest of an oligosaccharide
R3: may be H or α(1-6)-linked fucose

Applications: 
To obtain efficient deglycosylation of glycoprotein substrates under non-denaturing conditions, it is necessary to use a higher starting concentration of enzyme. N-Glycanase® PLUS and ULTRA (EDTA-Free) are supplied at ≥ 10 U/ml, and are recommended for all applications requiring deglycosylation of glycoproteins in the absence of denaturants. The high activity also allows smaller reaction volumes and shorter reaction times to be explored.
