Human cytomegalovirus (HCMV) G

分子别名（Synonym）:gB 种属（Species）：CMV 表达系统（Expressed Host）：HEK293 Cells 制剂（Buffer）：Lyophilized from sterile 100mM Gly, 10mM NaCl, 50mM Tris, pH 7.5 分子量（Molecule Mass）：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. 内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method. 生物活性(Activity)：Measured by its ability to bind biotinylated Human CD209-Fc (Cat:H1424-201H) in functional ELISA. 表达区间（Protein Construction）：A DNA sequence encoding the extracellular domain (Ser 2-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. 存储条件（Storage）： For long term storage, the product should be stored at lyophilized state at -20℃ or lower.Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at:4-8℃ for 12 months in lyophilized state;-70℃ for 3 months under sterile conditions after reconstitution. 运输条件： 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.
