技术参数

分子别名 (Synonym)

S1 protein; Spike protein S1; Spike,S1 protein; S glycoprotein Subunit1

来源/表达系统 (Source)

Recombinant SARS-COV-2 Spike S1 Protein is expressed from HEK293 with hFc (IgG1) tag at the C-Terminus.It contains Val16-Arg685 [Accession | QHO60594.1].

分子量

The protein has a predicted MW of 101.6 kDa. Due to glycosylation, the protein migrates to 115-130 kDa based on Bis-Tris PAGE result.

内毒素 (Endotoxin)

Less than 1 EU per μg by the LAL method.

纯度 (Purity)

> 95% as determined by Bis-Tris PAGE

制剂 (Formulation)

Supplied as 0.22μm filtered solution in PBS (pH 7.4).

存储 (Storage)

Valid for 12 months from date of receipt when stored at -80°C. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

Recombinant SARS-CoV-2 spike S1-Fc fusion protein induced high levels of neutralizing responses in nonhuman primates. Vaccine. 2020 Jul 31;38(35):5653-5658. doi: 10.1016/j.vaccine.2020.06.066 Epub 2020 Jun 24. PMID: 32651113; PMCID: PMC7311893.

背景介绍

The spike protein (S) of coronavirus (CoV) attaches the virus to its cellular receptor, angiotensin-converting enzyme 2 (ACE2). A defined receptor-binding domain (RBD) on S mediates this interaction.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.
