| Bioactivity | X-Neu5Ac (sodium) is a substrate for chromogenic assay of neuraminidase activity in bacterial expression systems; with a Km of 0.89 mM for neuraminidase. |
| Target | Km: 0.89 mM (neuraminidase) |
| Invitro | X-Neu5Ac (sodium) is a good substrate (Km=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]. MCE has not independently confirmed the accuracy of these methods. They are for reference only. 0 --> X-Neu5Ac sodium 相关抗体: |
