General description

Note: 1 mU = 1 milliunit.
Recombinant, Elizabethkingia meningosepticum endoglycosidase F2 expressed in E. coli. Cleaves asparagine-linked or free oligomannose and biantennary complex oligosaccharides from glycoproteins. It cleaves between the two N-acetylglucosamine residues in the diacetylchitobiose core of the oligosaccharide generating a truncated sugar molecule with one N-acetylglucosamine residue remaining on the asparagine. Less sensitive to protein conformation than N-Glycosidase F (Cat. No. 362185) and therefore is more suitable for deglycosylation of native proteins. This enzyme is not active above pH 6.0.

Physical form

In 25 mM NaCl, 10 mM sodium acetate buffer, pH 4.5.

Other Notes

One unit is defined as the amount of enzyme that will release N-linked oligosaccharides from 1 µmol porcine fibrinogen per min at 37°C, pH 4.5.
