Viral Proteins
Spike, RBD, nucleocapsid and envelope antigens from SARS-CoV-2 and other viruses — including biotinylated formats — for serology, vaccine and neutralisation research.
By protein type
By species
Yes — recombinant antigens such as spike RBD and S1 are widely used as capture antigens in serology ELISAs and neutralisation assays. Biotinylated versions bind streptavidin surfaces in a defined orientation.
Proteins are typically purified to ≥95%, confirmed by SDS-PAGE. Purity, tag and expression host are listed on each datasheet.
Typical lead time is 7–10 business days.
