分子别名（Synonym）:CD279,hPD-1,hPD-l,hSLE1,PD-1,PD1,SLEB2

种属（Species）：Human

表达系统（Expressed Host）：HEK293 Cells

产品状态（Buffer）：Lyophilized from sterile PBS, pH 7.4

分子量（Molecule Mass）：The recombinant human PD1/Fc is a disulfide-linked homodimeric protein. The reduced monomer consists of 390 amino acids and has a calculated molecular mass of 44 kDa. As a result of glycosylation, rhPD1/Fc monomer migrates as an approximately 60-65 kDa protein in SDS-PAGE under reducing conditions.

内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method.

生物活性(Activity)：Measured by its binding ability in a functional ELISA

表达区间（Protein Construction）：A DNA sequence encoding the extracellular domain (Ser 2-Gln 167) of human PD1 (NP_005009.2) was fused with the C-terminal polyhistidine-tagged 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.
