Description

Application

Neurminidase is used as a cell-surface probe for glycoconjugate distribution and in substrate specificity studies.

Other Notes

As a cell-surface probe of glycoconjugate distribution; Substrate specificity studies

1 U corresponds to the amount of enzyme which releases 1 μmol N-acetylneuraminic acid per minute at pH 4.5 and 37 °C (Neu5Acα(2-3,6)Galβ(1-4)Glc as substrate)
