Recombinant Cytomegalovirus UL55 protein, Fc-tagged

Cat.No.: UL55-181C
Product Overview: Recombinant Cytomegalovirus gB(Met 1-Lys 700, 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.
Description: 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.
Source: HEK293
Species: Cytomegalovirus
Tag: Fc
Predicted N Terminal: Asn 2
Form: Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Molecular Mass: The recombinant human CMV glycoprotein B ECD/Fc is a disulfide-linked homodimer after removal of the signal peptide. The reduced monomer consists of 914 amino acids and has a predicted molecular mass of 104 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of the monomer is approximately 135-145 kDa due to glycosylation.
Protein length: Met 1-Lys 700
Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
Purity: > 80 % as determined by SDS-PAGE
Stability: Samples are stable for up to twelve months from date of receipt at -70 centigrade
Storage: Store it under sterile conditions at -20 centigrade to -80 centigrade. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution: A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
Shipping: In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
