Antigendetails

Target: SARS-CoV-2 Spike

Abstract: SARS-CoV-2 Spike Produkte

Synonyme: E2 Protein, E2 glycoprotein precursor Protein, Surface Glycoprotein Protein, S Protein

Substanzklasse: Viral Protein

Hintergrund: The spike protein (S) of coronavirus (CoV) attaches the virus to its cellular receptor, angiotensin-converting enzyme 2 (ACE2). A defined receptor-binding domain (RBD) on S mediates this interaction.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.

Molekulargewicht: 136.70 kDa. Due to glycosylation, the protein migrates to 140-180 kDa based on Tris-Bis PAGE result.
