Influenza Neuraminidase Inhibitor Susceptibility Assay Kit
產品描述:神經氨酸酶(EC 3.2.1.18)是四聚體Ca 2+依賴性唾液酸酶,其從糖蛋白的寡糖鏈切割末端唾液酸殘基的α-糖苷鍵。神經氨酸酶家族酶存在於大多數從細菌到人類的生命形式中,並且也由幾種病毒基因組(包括流感病毒)編碼。流感病毒神經氨酸酶通過防止複制後代病毒顆粒的自我聚集並使感染的宿主細胞釋放活性流感病毒顆粒而在病毒的複制和傳播中起關鍵作用。競爭性阻斷新合成病毒顆粒的酶介導釋放的神經氨酸酶抑制劑被廣泛用作抗流感藥物。病毒神經氨酸酶的快速突變可產生更具致病性的新的流感病毒株,並且還對現有的神經氨酸酶抑制劑產生抗性。因此,監測世界範圍內收集的流感病毒分離株的神經氨酸酶活性和抑制劑易感性,對於確定新的流感大流行毒株和指導公共衛生戰略以控制季節性流感流行是不可或缺的。 BioVision的流感神經氨酸酶活性/抑制劑易感性分析試劑盒能夠利用轉化為穩定的高度熒光產物(Ex / Em = 368 / 460nm)的熒光底物快速測量病毒神經氨酸酶活性。該測定允許對流感病毒分離株中的基線神經氨酸酶活性和抑制劑易感性模式進行高通量功能性篩選,以評估新型抑制劑抗性株的可能出現。符合最新的CDC和WHO研究指南的簡單,標準化的方案確保流感病毒抗藥性易感性監測的可再現神經氨酸酶抑制劑IC50數據。該測定也可用於篩選針對已知的耐藥性流感毒株的新型神經氨酸酶抑制劑。該試劑盒包括足夠的試劑,以96孔板的形式進行至少1000次反應(10個試驗板)。。
