產品描述：

制備重組小鼠唾液酸酶-4 (Neu4)的一般步驟：
獲取并克隆Neu4基因：從小鼠組織中提取總RNA，利用逆轉錄酶和PCR擴增技術獲得Neu4基因。將擴增后的Neu4基因插入到表達載體中，如pET系列載體中。

轉染宿主細胞：將含有Neu4基因的表達載體轉染到宿主細胞中。可以選擇常見的哺乳動物細胞系，如CHO細胞、HEK293細胞等。

表達Neu4蛋白：根據表達載體中的啟動子和調節元件，誘導Neu4蛋白在轉染的宿主細胞中表達。在培養期間，需要添加抗生素等來保持表達載體的穩定。

收集細胞裂解液：利用細胞破碎和離心等方法，收集含有Neu4蛋白的細胞裂解液。

純化Neu4蛋白：采用親和層析、離子交換層析、凝膠過濾層析等方法對Neu4蛋白進行純化。

鑒定和活性檢測：使用SDS-PAGE、Western blot等方法對純化后的Neu4蛋白進行鑒定和定量。此外，可以使用唾液酸酶活性分析等方法來檢測其生物學活性和功能。

需要注意的是，唾液酸酶是一種糖酶，需要在適當的pH和溫度下進行表達和純化。此外，唾液酸酶在儲存和使用時容易受到蛋白質降解酶的影響，因此需要注意保存條件。

靶點詳情

功能：

Exo-alpha-sialidase that catalyzes the hydrolytic cleavage of the terminal sialic acid (N-acetylneuraminic acid, Neu5Ac) of a glycan moiety in the catabolism of glycolipids, glycoproteins and oligosacharides. Efficiently hydrolyzes gangliosides including alpha-(2->3)-sialylated GD1a and GM3 and alpha-(2->8)-sialylated GD3. Hydrolyzes poly-alpha-(2->8)-sialylated neural cell adhesion molecule NCAM1 likely at growth cones, suppressing neurite outgrowth in hippocampal neurons. May desialylate sialyl Lewis A and X antigens at the cell surface, down-regulating these glycan epitopes recognized by SELE/E selectin in the initiation of cell adhesion and extravasation. Has sialidase activity toward mucin, fetuin and sialyllactose.
