High SARS-CoV-2 incidence and asymptomatic fraction during Delta and Omicron BA.1 waves in The Gambia Many low- and middle-income countries, including The Gambia, had low COVID-19 vaccination coverage during the emergence of the Delta and Omicron variants. Here, the authors perform a prospectiv...
Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a recently identified coronavirus strain responsible for the Coronavirus Disease 2019 (COVID-19) and pandemic. SARS-CoV-2 is transmitted mainly through droplets and surface contact routes. The virus infects human cells through interactio...
图片:这张图显示了SARS-CoV-2表面的一系列刺突蛋白。每种颜色的抗体代表每个RBD社区可能的IgG-Spike结合模式。 出处: 经Hastie等人许可转载,来自《科学》(2021) 有些人认为疫情最糟糕的日子早就过去了,但新的病毒变异不断出现,疫苗标兵以色列破防,美国COVID-19病例再次升高,世界各地许多人将多年得不到COVID-19疫...
使用HIV-1(人类免疫缺陷I 型病毒)为基础载体侵染293T细胞后,包装成SARS-CoV-2 (2019-nCoV) Spike假病毒,表面表达SARS-CoV-2 (2019-nCoV) Spike蛋白,并携带有荧光素酶报告基因,可用于侵染过表达ACE2的细胞,荧光素酶在细胞内表达。此假病毒无自主复制能力,具有安全性高、可操作性强等特点。
SARS-CoV-2 Spike Antibody (clone AM005415) tested by ELISA.SARS-CoV-2 Spike RBD protein was coated onto microtiter plates at 0.5 µg/mL and then incubated with a dilution series of SARS-CoV-2 Spike Antibody (clone AM009105). Bound antibodies were detected with anti-human IgG conjugated ...
b Structure of SARS-CoV-2 Omicron spike protein mapped with the novel mutations. Mutated residues in each domain of the spike protein are annotated in color (red: RBD; yellow: NTD; green: S1/S2; blue: S2) using with Pymol 2.0 software through SARS-CoV-2 Omicron model PDB:7WBL and 7...
SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) also known as 2019-nCoV (2019 Novel Coronavirus) is a virus that causes illnesses ranging from the common cold to severe diseases. SARS-CoV-2 Spike Protein is composed of S1 domain and S2 domain. S1 contains a receptor-binding dom...
在这项研究中,我们测量了对最近SARS-CoV-2株的刺突糖蛋白进行的成千上万次突变,对病毒演变至关重要的三个分子表型的影响: 1.细胞入侵 2.ACE2结合 3.人体多克隆血清的中和作用(图1a)。 为了做到这一点,我们最近扩建了描述的一个假病毒载体深度突变扫描系统【4】,该系统可以安全地对整个刺突进行突变的实验性表...
