One unit will liberate 1.0 micromole of N-acetyl neuraminic acid per minute at pH 5.0 at 37 °C using bovine submaxillary mucin.One unit will hydrolyze 1.0 micromole of 2′-(4-methylumbelliferyl)-a-D-N-actetylneuraminic acid per minute at pH 5.0 at 37 °C (using 4MU-NANA as a substrate)
Purity
Type VIII, lyophilized powder, 10-20 units/mg protein (using 4MU-NANA), 3.5-8.0 units/mg protein (mucin)
Applications
Neuraminidase from Clostridium perfringens has been used to evaluate the binding properties of iodine toxin by fluorescence activated cell counting. It can promote the release of influenza virus.
