SARS-CoV-2 IgM ELISA Kit
產品介紹:. 冠狀病毒(Coronaviruses)是大型的脂質包裹(lipid-enveloped)的單鏈RNA病毒(single-stranded RNA viruses),已知可感染多種宿主,包括人(humans),蝙蝠(bats),小鼠(mice)和其他哺乳動物(mammals)。在七種已知的人類冠狀病毒(human coronaviruses)中,MERS-CoV,SARS-CoV-1和SARS-CoV-2是最致病的,會引起嚴重的,可能致命的呼吸道(fatal respiratory)和心血管症狀(cardiovascular symptoms)。新型SARS-CoV-2病毒的出現是造成2019年冠狀病毒疾病(COVID-19)大流行的原因,已被證明是21世紀最大的公共衛生危機(public health crisis)。SARS-CoV-2具有〜30 kb的基因組(genome),編碼29種蛋白質,包括用於病毒體裝配的4種結構蛋白質(structural proteins),即Envelope (E),膜(Membrane ,M),核仁(Nucleocapsid ,N)和穗(Spike ,S)蛋白質。跨膜刺蛋白(transmembrane Spike protein)是負責宿主細胞結合和病毒進入的糖蛋白(glycoprotein)。它是具有兩個獨特亞基的異三聚體複合物(heterotrimeric complex)。 S1亞基包含受體結合域(Receptor Binding Domain),其與作為宿主細胞受體的血管緊張素轉化酶2(Angiotensin-Converting Enzyme 2)相互作用,而S2亞基介導病毒膜融合(S2 subunit mediates viral membrane fusion)。 S蛋白是高度免疫原性的,通常在症狀發作後5-21天之間檢測到感染個體的血清轉化(seroconversion)。 BioVision的SARS-CoV-2 IgM ELISA試劑盒是一種酶聯免疫吸附測定(enzyme-linked immunosorbent assay),旨在鑑定對SARS-CoV-2感染的早期免疫反應。該測定法使用刺突蛋白S1亞基(spike protein S1 subunit)作為誘餌來捕獲稀釋的血漿或血清樣品中的抗SARS-CoV-2抗體(anti-SARS-CoV-2 antibodies)。隨後與酶標記的抗人IgM綴合物和比色底物反應產生顏色,該顏色與抗S1抗體的數量成比例。通過比較樣品的OD450 nm讀數與陰性對照血清的OD450 nm讀數來確定抗SARS-CoV-2 S1 IgM抗體(anti-SARS-CoV-2 antibodies)的存在。陽性反應提示近期感染,因為IgM抗體是暴露後最先出現的,通常在感染後幾天即可檢測到。試劑盒中包含含有重組人單克隆抗S1 IgM抗體(human monoclonal anti-S1 IgM antibody)的陽性對照血清(Positive control serum),用於驗證。該測定法是一種快速,簡便且準確的方法,可用於確定不需要收集或處理傳染性病毒的近期SARS-CoV-2感染。該套件是研究COVID-19流行病學,患病率和發病率的工具。

Kit Summary | BioVision’s SARS-CoV-2 IgM ELISA Kit is an enzyme-linked immunosorbent assay intended for identifying the early immune response to SARS-CoV-2 infection. The assay uses the spike protein S1 subunit as bait to capture anti-SARS-CoV-2 antibodies in diluted plasma or serum samples. Subsequent reaction with an enzyme-labeled anti-human-IgM conjugate and a colorimetric substrate generates color, which is proportional to the amount of anti-S1 antibodies. The presence of anti-SARS-CoV-2 S1 IgM antibodies is determined by comparing the OD450 nm reading of the sample to the OD450 nm reading of the negative control serum. A positive reaction suggests recent infection, as IgM antibodies are the first to appear following exposure and are generally detectable a few days after infection. Positive control serum containing a recombinant human monoclonal anti-S1 IgM antibody is included in the kit for validation. The assay is a quick, easy and accurate method for determination of recent SARS-CoV-2 infection that does not require collection or handling of infectious virus. This kit is a valuable tool to study COVID-19 epidemiology, prevalence and morbidity. |
