Active Recombinant SARS-CoV S1 Subunit Protein, His-tagged

• Cat.No.: S-05S
• Product Overview: Recombinant SARS-CoV spike S1 subunit (14-667 aa) fused to His-tag at C-terminus, was expressed in HEK293 cell and purified by using conventional chromatography techniques.

Specification

• Species: SARS-CoV
• Source: HEK293
• Tag: His
• Protein Length: 660
• Description: attaches the virion to the cell membrane by interacting with host receptor, initiating the infection. Binding to human ACE2 and CLEC4M/DC-SIGNR receptors and internalization of the virus into the endosomes of the host cell induces conformational changes in the S glycoprotein. Proteolysis by cathepsin CTSL may unmask the fusion peptide of S2 and activate membranes fusion within endosomes.
• Form: Liquid
• Bio-activity: Measured by its binding ability in a functional ELISA with Human ACE-2.
• Molecular Mass: 73.7kDa
