HEK293
Protein is >85% pure as determined SDS-PAGE.
The HEK293 derived recombinant protein contains the Novel Coronavirus 2019-nCoV Spike Glycoprotein S1, Wuhan-Hu-1 strain, amino acids 1-674 fused to Fc tag at C-terminal.
In December 2019, a novel coronavirus, designated as 2019-nCoV, emerged in Wuhan, China, causing viral pneumonia in humans. The virus was initially linked to a seafood market.
Genetic analysis revealed that 2019-nCoV shares a high degree of similarity (87%) with a bat-derived SARS-like coronavirus (SARS-CoV-2) discovered in Zhoushan, China. Despite some genetic variations, the receptor-binding domain (RBD) of 2019-nCoV closely resembles that of SARS-CoV, suggesting a potential to bind to the human ACE2 receptor.
While bats are suspected to be the natural reservoir of 2019-nCoV, an intermediate animal host, possibly traded at the Wuhan market, is thought to have played a role in its transmission to humans. Research indicates that 2019-nCoV might have arisen from a recombination event involving a bat coronavirus and another unknown coronavirus, particularly in the spike glycoprotein region.
This recombinant protein consists of the Spike Glycoprotein S1 subunit (amino acids 1-674) of the 2019 Novel Coronavirus (2019-nCoV), specifically the Wuhan-Hu-1 strain. It is produced in HEK293 cells and is fused with an Fc tag at its C-terminus.
The nCoV-S1 protein solution is provided in a solution of Dulbecco's Phosphate-Buffered Saline (DPBS) at a pH of 7.4.
To maintain product integrity, the protein is shipped with ice packs to ensure a cool temperature during transport. Upon receiving the protein, it should be stored at a temperature of -20 degrees Celsius.
The purity of the protein is greater than 85%, as determined by SDS-PAGE analysis.

The Coronavirus 2019 Spike Glycoprotein-S1 (SARS-CoV-2 Spike S1) is a crucial component of the virus responsible for the COVID-19 pandemic. This glycoprotein plays a pivotal role in the virus’s ability to infect host cells. The recombinant form of this protein is widely used in research and vaccine development.
The Spike (S) glycoprotein of SARS-CoV-2 is a trimeric protein that protrudes from the viral surface. It is divided into two subunits: S1 and S2. The S1 subunit contains the receptor-binding domain (RBD), which is responsible for binding to the host cell receptor, angiotensin-converting enzyme 2 (ACE2). This binding is the first step in the viral entry process .
Recombinant SARS-CoV-2 Spike S1 proteins are produced using various expression systems, including HEK293 cells and CHO cells. These systems allow for the production of high-purity proteins suitable for research applications. The recombinant proteins are often tagged with polyhistidine (His) tags to facilitate purification .
