SIAE 蛋白, Human (sf9, His)

SIAE proteins play a key role in cellular processes by catalyzing the removal of the O-acetyl ester group specifically from the 9-position of the parent sialic acid N-acetylneuraminic acid. Through this enzymatic activity, SIAE helps regulate sialic acid modifications, affecting various biological functions associated with cell surface glycoconjugates. SIAE Protein, Human (sf9, His) is the recombinant human-derived SIAE protein, expressed by Sf9 insect cells , with C-His labeled tag.

SIAE（唾液酸乙酰酯酶）蛋白是一种酶，通过催化去除母体唾液酸 N-乙酰神经氨酸的 9 位 O-乙酰酯基团，在唾液酸代谢中发挥至关重要的作用。这种酶活性对于调节唾液酸的结构修饰非常重要，唾液酸是糖蛋白和糖脂的重要组成部分。SIAE 介导的第 9 位脱乙酰作用影响唾液酸的整体电荷和结构，从而影响细胞相互作用、免疫反应和信号转导。了解 SIAE 的功能可以深入了解唾液酸修饰的动态调节及其对各种生理过程的影响。参考资料：所提供的信息基于截至 2022 年 1 月的一般知识，未引用具体参考资料。

Lyophilized from a 0.2 μm filtered solution of 20 mM Tris, 500 mM NaCl, pH 8.0. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
