tcsc0769 X-Neu5Ac

X-Neu5Ac is a substrate for chromogenic assay of neuraminidase activity in bacterial expression systems; with a K_m of 0.89 mM for neuraminidase.

IC50 & Target: Km: 0.89 mM (neuraminidase)^[1]

In Vitro: X-Neu5Ac is a good substrate (K_m=0.89 mM) for neuraminidase and is quite stable under identical conditions in the absence of enzyme^[1]. Staining with X-Neu5Ac and FRV LB is specific for sialidase and useful for quantitative analysis of sialidase activities^[2].
