Sialidase (Pan, His tag)

Sialidase (Pan, His tag) 是一種專門水解醣蛋白上 sialic acid(唾液酸)的酵素,亦被稱為神經胺酸酶。這種酵素在許多病原體,特別是流感病毒的表面上都可以找到。其主要功能是破壞宿主細胞表面的唾液酸結構,從而協助病原體穿透並感染宿主細胞。這一特性使得唾液酸酶在病原體的生物學和病理學中扮演了關鍵角色。

  • Official Name: Pan Sialidase
  • Specificity: Sialidase (Pan) catalyzes the hydrolysis of terminal α-linked N-acetylneuraminic acid (Neu5Ac) from oligosaccharides, complex carbohydrates, and glycoproteins. No detectable activities of proteases or other glycosidases are observed.
  • Content: Purified lyophilized powder
  • Tag: 8x His tag at N-term, which can be removed by digestion with FasTEV
  • Reconstitution: Dissolve the lyophilized product in 100 μL of molecular grade water to make a 50,000 units/ml solution in the buffer.
  • Buffer: 50 mM EPPS, 100 mM NaCl, pH 7.5
  • Storage: -20 °C as powder. Once reconstituted, 4 °C for five days  or -20 °C for up to three months. Avoid freeze-thaw cycles.
  • Unit Definition: One unit is defined as the amount of Sialidase (Pan) required to catalyze the release of 1 nanomole of p-nitrophenol (pNP) from 2-O-(p-nitrophenyl)-α-D-N-acetylneuraminic acid (pNP-Neu5Ac) in 1 min at 37°C in 100 μL 1X Reaction Buffer 4 (50 mM Tris-HCl, 100 mM NaCl, pH 7.5).
