Product Specific Information
This antibody binds the amino acids 318–510 in the S1 domain of the SARS-CoV Spike protein as well as SARS-CoV-2 (COVID-19) Spike protein.
It also binds to P462L-substituted S318–510 fragments of the SARS spike protein.
Target Information
The SARS-CoV-2 virus, responsible for the COVID-19 pandemic, has a spike protein composed of two subunits, S1 and S2.
The S1 subunit binds to the human ACE2 receptor, initiating viral entry and host cell recognition.
SARS-CoV spike protein S1, active during the 2002–2003 outbreak, shares high similarity with SARS-CoV-2 S1, though amino acid differences may affect ACE2 binding affinity.
Both spike proteins have a trimeric structure, with each subunit consisting of two domains:
- N-terminal domain (NTD) – involved in recognition of other host factors
- Receptor-binding domain (RBD) – binds to the ACE2 receptor
