The fusion glycoprotein F0/F protein is initially an inactive precursor that is cleaved by furin-like proteases to produce the mature F1 and F2 fusion glycoproteins. As a class I viral fusion protein, it undergoes prefusion, prehairpin, and postfusion states. Fusion glycoprotein F0/F Protein, HRSV (His, B2M) is the recombinant Virus-derived Fusion glycoprotein F0/F protein, expressed by E. coli , with N-B2M, N-6*His labeled tag.
