Coronavirus Spike protein is extensively glycosylated viral fusion protein, containing several N-linked glycosylation sites per trimeric spike. Because Env is heavily glycosylated compared to host glycoproteins, the glycans have become targets for the antibody response and vaccine production. This unique glycan structure can be captured by specific Lectins and Glycomatrix makes Vigna radiata (Mungbean) lectins functionalized with biotin (SKU: 21510942) or coupled to magnetic beads to enrich the spike protein or virus for detection or protein analysis as well as antibody titration in serum.
