• Material Safety Data Sheets (MSDS)

Human cytomegalovirus (CMV) (human herpesvirus 5) glycoprotein B, also referred as CMV gB or gB, which belongs to the herpesviridae glycoprotein B family. It is a 907-amino acid glycoprotein encoded by the ORF of UL55. Cytomegalovirus Glycoprotein B protein is the most abundant component of the envelope, a target of neutralizing antibodies with at least two defined neutralizing epitopes and an essential replication component. Cytomegalovirus Glycoprotein B protein plays important roles in HCMV entry, cell-cell spread of internal virions, and fusion of infected cells. In addition, Cytomegalovirus Glycoprotein B protein is one envelope protein capable of heparin binding. It forms a physical association with host cell annexin II independent of the presence of calcium.

Human Cells

A DNA sequence encoding the extracellular domain (Met 1-Lys 700) linked with the cytoplasmic domain (Arg 777-Val 907) of human CMV gB (AAA45920.1, with furin cleavage site mutated from 'RTKR' to 'TTQT') precursor was fused with the Fc region of human IgG1 at the C-terminus.

CMV

The recombinant human CMV glycoprotein B/Fc is a disulfide-linked homodimer after removal of the signal peptide. The reduced monomer consists of 1045 amino acids and has a predicted molecular mass of 118 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of gB/Fc monomer is approximately 160-170 kDa due to glycosylation.
