MERS-CoV Spike/S RBD (sf9, His)

Room temperature

The SARS-CoV Spike glycoprotein (S) has three subunits S1, S2' and S2 through alternative splicing. The engagement of the MERS-CoV spike protein S1 with CD26 (also known as dipeptidyl peptidase 4, DPP4) mediates viral attachment to host cells and virus鈥揷ell fusion, thereby initiating infection. S2 mediates fusion of the virion and cellular membranes by acting as a class I viral fusion protein and S2' is unmasked following S2 cleavage occurring upon virus endocytosis. MERS-CoV Spike/S Protein RBD (sf9, His) is the recombinant Virus-derived MERS-CoV Spike/S protein RBD, expressed by Sf9 insect cells , with C-His labeled tag.
