Application
神经氨酸酶是一种重要的去糖基化酶，能够通过水解 α (2→6)、α (2→3)、α (2→8) 和 α (2→9) 键（按给定的顺序亲和力）裂解所有非还原的不分枝 N-乙酰神经氨酸和 N-羟乙酰神经氨酸残基。使用高浓度的酶和延长孵育时间也可裂解分支的唾液酸。脱唾液酸糖蛋白可通过用各种外切糖苷酶处理进一步表征，导致部分或完全 O-脱糖基化。SDS-PAGE 和 MALDI-TOF MS 通常用于纯化、结构分析和测序过程。这些技术还可去除糖蛋白的异质性和电荷。
Packaging
提供 5× 浓缩液反应缓冲液。
Physical form
冻干粉末
Analysis Note
专门配制了缓冲液，以确保最大的酶稳定性和试验灵敏度。
Other Notes
在 37°C、pH 值为 5.5 的条件下，1 个单元每分钟从 2-（4-甲基伞形酮）α-D-N-乙酰神经氨酸中释放 1 nmol 4-甲基伞形酮。

Last decade witnessed an enormous progress in generating authentic infectious prions or PrPSc in vitro using recombinant prion protein (rPrP). Previous work established that rPrP that lacks posttranslational modification is able to support replication of highly infectious PrPSc with assistance

Recent studies have shown that cerebral apoD levels increase with age and in Alzheimer's disease (AD). In addition, loss of cerebral apoD in the mouse increases sensitivity to lipid peroxidation and accelerates AD pathology. Very little data are available, however

Interactions that facilitate transmembrane domain (TMD) dimerization have been identified mainly using synthetic TMDs. Here, we investigated how inherent properties within natural TMDs modulate their interaction strength by exploiting the sequence variation in the nine neuraminidase subtypes (N1-N9) and the
