SARS-CoV-2 (2019-nCoV) 重組N蛋白IgM抗體ELISA檢測試劑盒 | Abebio

 

人類冠狀病毒在20世紀60年代首次在普通感冒患者的鼻子中發現，因在電子顯微鏡下可觀察到病毒外表的冠狀構造而得名“冠狀病毒”。據悉，15%到30%的普通感冒都是由這些病毒導致的。

冠狀病毒是由單一的核糖核酸(RNA)構成，這種RNA和N蛋白共同組成病毒。由於其遺傳物質是RNA，因此非常容易出現變異。冠狀病毒屬於巢狀病毒目的冠狀病毒科，為單鏈RNA病毒，分為ɑ、ß、γ、δ四個屬。

2019新型冠狀病毒，即2019-nCoV，因2019年武漢病毒性肺炎病例而被發現，2020年1月12日被世界衛生組織命名。和2003年的SARS冠狀病毒以及2012年的MERS冠狀病毒同屬於冠狀病毒科β屬。2019-nCoV與2003年”非典”SARS CoV比對，有約70%序列相似性，與MERS CoV有40%的序列相似性。

2019-nCoV經過呼吸道飛沫和接觸是主要的傳播途徑。人群普遍易感，老年人及有基礎疾病者感染後病情較重，兒童及嬰幼兒也有發病。對紫外線和熱比較敏感，56°C 30分鐘、乙醚、75%乙醇、含氯消毒劑、過氧乙酸和氯仿等脂溶劑均可有效殺滅活病毒。

新型冠狀病毒（2019-nCoV）的診斷方法有病毒分離、抗原直接檢測（咽拭子或肺泡灌洗液）、PCR擴增和血清學方法以及基因測序等。由於血清標本來源方便而穩定，臨床上最易獲得，尤其新冠病毒感染主要以下呼吸道為主，因此血清標本比肺泡灌洗液標本更便利。

新型冠狀病毒IgM抗體於感染後最早可在3-7天內出現，因此對於早期診斷及協助PCR方法篩查隱性感染者具有較大優勢。一般情況下，IgG和IgA抗體在4-8周內出現。通常IgM在感染後2-6個月下降，IgA抗體亦下降，IgG抗體下降緩慢。當反復感染或慢性感染時，IgM的滴度通常很低，而IgG抗體會迅速增高（常呈4倍以上升高）。因此，IgM抗體檢測呈陰性時並不能排除現症感染的可能，再次感染時，IgM抗體通常可能不會出現，而IgG抗體的滴度會迅速升高。IgG抗體的檢測用於協助再次感染和流行病學調查。
