Product Description
The N-Glycosidase PNGase F is recombinant enzyme cloned from
Elizabethkingia miricola. It has molecular weight of ~36 Kda. PNGase F catalyzes the cleavage of N-linked oligosaccharides
between the innermost GlcNAc and asparagine residues of high mannose, hybrid and complex oligosaccharides from N-linked glycoproteins. PNGase F will not remove oligosaccharides containing Alpha- (1,3)-linked core fucose commonly found
on plant glycoproteins. Glycerol free, EDTA free standard Buffer is preferred choice for HPLC, UPLC and LC-MS glycoprotein
samples.
Source: An E. coli strain that carries the gene which express PNGase F.
