Invitrogen™ SARS-CoV-2 Spike Protein (RBD) (P.1) Fc Chimera Recombinant Protein

Description

Recombinant Protein

It is recommended that the protein be aliquoted for optimal storage. It is recommended that sterile water (400 μL) be added to the vial to prepare a stock solution of 0.25 mg/mL. Concentration is measured by UV. The mutations were identified in the SARS-CoV-2 varient known as P.1

SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) also known as 2019-nCoV (2019 Novel Coronavirus) is a virus that causes illnesses ranging from the common cold symptoms to severe effects including death and respiratory distress. The CoV Spike (S) protein plays the most important roles in viral attachment, fusion and entry, and serves as a target for development of antibodies, entry inhibitors and vaccines. Of note is the Spike protein receptor-binding domain (RBD, S-RBD) in SARS-CoV-2 Spike protein which binds strongly to human and bat angiotensin-converting enzyme 2 (ACE2) receptors. SARS-CoV-2 RBD exhibits significantly higher binding affinity to ACE2 receptor than SARS-CoV RBD in comparison. S1 contains a receptor-binding domain (RBD) that can specifically bind to angiotensin-converting enzyme 2 (ACE2), the receptor on target cells.
