人抗SARS-CoV-2 (2019-nCoV) S蛋白单克隆IgG1抗体(hek293表达重组蛋白)

概述

抗sars - cov -2刺突蛋白S1受体结合域抗体克隆Covi-2(阻断/重组抗体)与sars相关冠状病毒2 (SARS-CoV-2/2019-nCoV)表达的刺突蛋白S1受体结合域(RBD)反应。

刺突蛋白是一种存在于冠状病毒(CoV)表面的I型跨膜糖蛋白。冠状病毒进入宿主细胞是由S蛋白介导的,它与细胞表面受体血管紧张素转换酶2 (ACE2)相互作用。在人类中,ACE2在几个器官和组织中表达,包括肠和呼吸上皮。

S蛋白有两个亚基S1和S2,其中S1主要由193个氨基酸的长RBD和n端结构域(NTD)组成。S2结构域负责膜融合。在冠状病毒感染过程中,S蛋白被宿主蛋白酶裂解为n端S1亚基和c端S2亚基,其构象由融合前状态转变为融合后状态。S蛋白已被证明在诱导中和抗体和T细胞反应中起关键作用,这可能导致保护性免疫。RBD与ACE2结合,而NTD的功能尚不清楚。Covi-2抗体阻断S1亚基与ACE2受体的相互作用,并结合与Covi-1抗体不同的表位。

Data Figures

Data figures showing that the binding between recombinant human ACE2 to the Spike protein S1 RBD is inhibited in the presence of increasing concentration of Covi-2 antibody.

Figure 1. Inhibitory Effect of Covi-2 Antibody on Spike Protein Receptor-Binding Domain and ACE2 Interaction

ELISA binding assay shows that at high concentrations, Anti-SARS-CoV-2 Spike Protein S1 Receptor-Binding Domain Antibody, Clone Covi-2 (Blocking/Recombinant) (orange line) blocks biotinylated recombinant human ACE2 from binding to an ELISA plate coated with recombinant SARS-CoV-2 Spike protein S1 RBD, in comparison to a negative control antibody (blue line). The binding of biotinylated recombinant human ACE2 to the Spike protein S1 RBD was detected using streptavidin horseradish peroxidase (HRP). The results were plotted as (A) absorbance (450 nm) or (B) binding percentage.
