    Note: The complete sequence may include tag sequence, target protein sequence, linker sequence and extra sequence that is translated with the protein sequence for the purpose(s) of secretion, stability, solubility, etc.
    If the exact amino acid sequence of this recombinant protein is critical to your application, please explicitly request the full and complete sequence of this protein before ordering.
  • 蛋白標簽：
    N-terminal 10xHis-tagged
  • 產品提供形式：
    Liquid or Lyophilized powder
    Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
  • 緩沖液：
    Lyophilized from Tris/PBS-based buffer, 6% Trehalose
  • 儲存條件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
  • 保質期：
    The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
    Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
  • 貨期：
    Basically, we can dispatch the products out in 1-3 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
    Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
  • 注意事項：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
  • 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?？梢赃x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(jù)表達載體中的啟動子和調節(jié)元件，誘導Neu4蛋白在轉染的宿主細胞中表達。在培養(yǎng)期間，需要添加抗生素等來保持表達載體的穩(wěn)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?shù)膒H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.
  • 基因功能參考文獻：
    1. These results provide the first in vivo evidence that neuraminidases 3 and 4 have important roles in CNS function by catabolizing gangliosides and preventing their storage in lipofuscin bodies. PMID: 28442549
    2. NEU4 is involved in regulation of neuronal function by polySia degradation in mammals. PMID: 22393058
    3. Neu4 is not the only sialidase contributing to the metabolic bypass in Hexa(-/-) mice. PMID: 20862357
    4. Neu4 is a functional component of the ganglioside-metabolizing system, contributing to the postnatal development of the brain and other vital organs. PMID: 18270209
    5. mouse Neu4 plays an important regulatory role in neurite formation, possibly through desialylation of glycoproteins PMID: 19506080
