  • Endoglycoceramidase I (EGCase I) catalyzes the hydrolysis of the β-glycosidic linkage between oligosaccharides and ceramides in various glycosphingolipids. The enzyme leaves the oligosaccharide and ceramide intact, keeping them suitable for further analysis. The enzyme efficiently releases oligosaccharides from ganglio- and globo-type glycosphingolipids, certain type of cerebrosides (glucosylcerebrosides), and exhibits low activity towards galactocerebrosides (See Reference 1, FAQ #3). EGCase I does not hydrolyze sulfatides nor psychosine.

    • Properties & Usage

      Unit Definition

      1 unit is defined as the amount of enzyme required to cleave >95% of the trihexose from 1 nmol of N-dodecanoyl-nitrobenzofurazan (NBD)-ceramide trihexoside in 30 minutes at 37°C in a total reaction volume of 10 µl.

      Reaction Conditions

      1X EGCase I Reaction Buffer
      Incubate at 37°C

      1X EGCase I Reaction Buffer
      50 mM sodium acetate
      0.1% Triton® X-100
      (pH 5.2 @ 25°C)

      Storage Buffer

      50 mM NaCl
      20 mM Tris-HCl
      1 mM EDTA
      pH 7.5 @ 25°C
