Active Recombinant SARS-CoV-2 Spike protein RBD Protein, HRP conjugated, His-tagged

• Cat.No.: S-1004S
• Product Overview: Recombinant 2019-nCoV Spike protein S1 subunit, RBD (319-541) was expressed in CHO cells using a C-terminal his tag, and then conjugated to Horse peroxidase (HRP).

Specification

• Species: SARS-CoV-2
• Source: CHO
• Tag: His
• Protein Length: 319-541 a.a.
• Description: The severe acute respiratory syndrome related novel coronavirus SARS-CoV-2 has caused the pandemic of the respiratory diseases (COVID-19) around the world in 2020. The spike glycoprotein (S) of coronavirus belongs to the type I transmembrane protein, which contains two subunits, S1 and S2, which is also known to be the key component to bind with host cells through the interaction with angiotensin-converting enzyme 2 (ACE2). A receptor binding domain (RBD) of S1 can recognize the cell surface receptor and the mutation of RBD could cause higher motility rate.
• Bio-activity: Binding ability measured in a functional ELISA. 2019-nCoV Spike protein RBD binds to immobilized human ACE2 (19-740) protein.
• Molecular Mass: 39 kDa
• Purity: > 90%
• Stability: One year at -20 centigrade from date of shipment.
• Storage: Store product at –70 centigrade. For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For most favorable performance, avoid repeated handling and multiple freeze/thaw cycles.
• Concentration: 0.2 μg/μL
• Storage Buffer: 1×PBS, pH 7.4 and 50% glycerol.
• Conjugation: HRP
