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.
Recombinant gene from Elizabethkingia meningosepticum, expressed in E. coli. The source organism was previously known as Chryseobacterium [Flavobacterium] meningosepticum .
Cleaves all N-linked complex, hybrid or high mannose oligosaccharides, unless α(1-3) core fucosylated, as in plant glycans and some insect 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.

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
"A & B" pack sizes ship with:
"D" pack size does not ship with the above buffers.
20 mM Tris-HCl, 50 mM NaCl, 1 mM EDTA (pH 7.5)
5X concentrated buffer, when diluted gives 20 mM sodium phosphate pH 7.5, containing 0.02% sodium azide.
8.6 / 7.5 - 9.5
One unit is defined as the amount of enzyme required to catalyze the release of N-linked oligosaccharides from 1 μmole of denatured ribonuclease B per minute at 37°C, pH 7.5.
Not formulated for FACE® analysis, use GK50050 instead.
