Application: SARS-CoV-2 Spike RBD (319–335)-Biotin-LC is a synthetic peptide corresponding to residues 319–335 of the spike receptor-binding domain, based on RefSeq YP_009724390.1. The RBD is essential for viral attachment to the human ACE2 receptor and is a major target for immune recognition. The C-terminal Biotin-LC label enables efficient immobilization, affinity capture, and detection in binding assays. This peptide is widely used in studies of viral entry mechanisms, antibody mapping, receptor interaction profiling, diagnostic assay design, and SARS-CoV-2 spike protein structure–function relationships.
