This peptide sequence represents a second furin-like cleavage site of the Spike (S) protein also thought to participate in the process of viral entry into host cell. The sequence at the S2 site (KR?SF) contains two basic residues (P1 and P2) and a hydrophobic P3 residue. This site is identical between the SARS-CoV-2 and SARS-CoV. This peptide has been labeled with QXL®520 and 5-FAM.
