Product Specific Information
The immunogen is located within the last 50 amino acids of SARS-CoV-2 (COVID-19, 2019-nCoV) Spike protein.
Predicted reactivity based on immunogen sequence: SARS-CoV Spike proteins (100%).
Target Information
SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2), also known as 2019-nCoV, causes illnesses ranging from mild cold symptoms to severe respiratory distress and death.
The CoV Spike (S) protein plays a critical role in viral attachment, fusion, and entry, serving as a key target for antibody development, entry inhibitors, and vaccines.
The receptor-binding domain (RBD, S-RBD) in SARS-CoV-2 Spike protein binds strongly to human and bat angiotensin-converting enzyme 2 (ACE2) receptors, showing higher affinity than SARS-CoV RBD.
- S1 subunit (amino acids 14–685): responsible for receptor binding
- S2 subunit (amino acids 686–1273): responsible for membrane fusion
- S-ECD: extracellular domain of the Spike protein
