Background

Endo H is a recombinant glycosidase cloned from Streptomyces plicatus and overexpressed in E.coli. It cleaves the chitobiose core of high-mannose oligosaccharides and a limited number of hybrid oligosaccharides from asparagine-linked glycoproteins, but not complex, oligosaccharides from glycoproteins.

Components

Storage Solution: 500U/μL EndoH (MBP Tag)、20 mM Tris-HCl、50 mM NaCl、5 mM EDTA (pH 7.5@ 25°C) 10*Denaturing Buffer: 5% SDS、400 mM DTT 10*Reaction Buffer: 500 mM sodium acetate(pH 6 @ 25°C)

Protocol

1. Combine 1-20 μg of glycoprotein, 1 μl of 10*Denaturing Buffer and H20 (if necessary) to make a 10 μl total reaction volume. 2. Denature glycoprotein by heating raection at 100°C for 10 minutes. 3. Make a total reaction volume of 20 μl by adding 2 μl of 10*Reaction Buffer, H20 and 1-5 μl Endo H (MBP Tag). 4. Incubate reaction at 37°C for 1 hour.

Guidelines

Please avoid repeated freeze-thaw cycles.

Unit Definition

One unit is defined as the amount of enzyme required to remove > 95% of the carbohydrate from 10 µg of denatured RNase B in 1 hour at 37°C in a total reaction volume of 10 µl.
