0181403 RECOMBINANT Store at C20°C Exp: 2/16 Description: Endo Hf is a recombinant protein fusion of Endoglycosidase H and maltose binding protein. Endo Hf cleaves the chitobiose core of?high mannose and some hybrid oligosaccharides from N-linked glycoproteins (1) equally as well as Endo H. Source: Cloned from Streptomyces plicatus (2) and overexpressed in?E. coli?(3) Applications: ? Removal of high mannose N-glycans from glycoproteins Supplied in:

50 mM NaCl,

20 mM Tris-HCl (pH?7.5 @ 25°C) and

5 mM Na2 EDTA. Reagents Supplied with Enzyme: 10X Glycoprotein Denaturing Buffer: 5% SDS, 0.4 M DTT 10X G5 Reaction Buffer: 0.5 M Sodium Citrate (pH 5.5 @ 25°C) Optimal incubation times and enzyme concentrations must be determined empirically for a particular substrate. G5 Reaction Buffer, two-fold dilutions of Endo Hf are added and the reaction mix is incubated for

1 hour at 37°C. Separation of reaction products are visualized by SDS-PAGE. Specific Activity: ~232,000 units/mg. Molecular Weight: 70,000 daltons. Quality Assurance: No contaminating exoglycosidase or proteolytic activity could be detected. Quality Controls Glycosidase Assays: 5,000 units of Endo Hwere incubated with 0.1 mM of flourescently-labeled oligosaccharides and glycopeptides, in a 10??l reaction for

20 hours at 37°C. The reaction products were analyzed by TLC for digestion of substrate. Physical Purity: Purified to >

95% homogeneity as determined by SDS-PAGE analysis using Coomassie Blue detection.
