SARS-CoV-2 S Protein
The spike glycoprotein of SARS-CoV-2 is the type I transmembrane trimer decorating the virion surface and executing receptor engagement followed by membrane fusion. This full-length recombinant form presents the complete ectodomain, spanning the S1 subunit with its N-terminal domain and receptor-binding domain through to the S2 fusion subunit, rather than any single isolated module. Proteolytic cleavage at the S1/S2 and S2' sites primes the protein, and preservation of the native prefusion conformation generally requires stabilising substitutions in expression constructs. As the immunogen behind nearly all authorised vaccines, full-length spike is the reference antigen for neutralising antibody titres, ACE2-blocking assays and variant cross-reactivity studies.

The EpCAM/TROP1 protein serves as an important homogeneous interacting molecule that promotes direct contact between intestinal epithelial cells (IEC) and intraepithelial lymphocytes (IEL) in the mucosal epithelium. This feature helps establish an immune barrier against mucosal infections. EpCAM/TROP1 Protein, Human (His-SUMO) is the recombinant human-derived EpCAM/TROP1 protein, expressed by E. coli , with N-6*His, N-SUMO labeled tag.
