Summary: Cat.No.: CD274-2330H Product Overview: Recombinant Human CD274 extracellular domain N-terminal segment (Met 1-Thr 239) (NP_054862.1), fused with C-terminal Fc region of human IgG1, was produced in Human Cell. Source: Human Cells Species: Human Tag: Fc Form: Lyophilized from sterile PBS, pH 7.4 Molecular Mass: The recombinant mature human B7-H1/Fc is a disulfide-linked homodimeric protein. The reduced monomer consists of 459 amino acids and predicts a molecular mass of 52 kDa. As a result of glycosylation, the rh B7-H1/Fc monomer migrates as an approximately 65-70 kDa protein in SDS-PAGE under reducing conditions.
