SARS-CoV-2 S1 蛋白 (Delta, B.1.617.2, His)

The SARS-Cov-2 S glycoprotein is a SARS-Cov-2 S glycoprotein. The amino acid sequence 1261-1267a.a of the SARS-Cov-2 S glycoprotein is transmembrane. The SARS-Cov-2 S glycoprotein is a highly glycosylated trimer, each of which consists of 1260 amino acids (residues 14-1273), divided into four structural domains: the n-terminal domain (NTD), the c-terminal domain (CTD, also known as the receptor-binding domain, RBD), and two subdomains (SD1 and SD2). SARS-CoV-2 S1 Protein (Delta, B.1.617.2, His) is the recombinant virus-derived SARS-CoV-2 S1, expressed by HEK293 , with C-10*His labeled tag. ,

SARS-Cov-2 是一种包膜阳性单链RNA病毒，可导致2019冠状病毒病(COVID-19)。
SARS-CoV-2 具有 4 种结构蛋白，包括包膜蛋白 (E)、刺突或表面糖蛋白 (S)、膜蛋白(M) 和核衣壳蛋白 (N)。
SARS-Cov-2 S glycoprotein 位于病毒颗粒的外部，使冠状病毒具有冠状外观。
ARS-Cov-2 S glycoprotein 可以介导病毒颗粒附着并进入宿主细胞，是疫苗开发、抗体治疗和基于抗原的诊断测试的重要靶标^{[1][2][3][4][5]}。

Immobilized ACE2 Protein, Human, Recombinant (mFc Tag) at 2 μg/mL (100 μL/well) can bind SARS-CoV-2 S1 Protein (Delta, B.1.617.2, His), the EC₅₀ is 30-180 ng/mL.
