分子别名（Synonym）:B7-H,B7-H1,B7H1,PD-L1,PDCD1L1,PDCD1LG1,PDL1

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 mature human B7-H1 comprises 232 amino acids and predicts a molecular mass of 26.8 kDa. As a result of glycosylation, the rh B7-H1 migrates as an approximately 35-38 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 N-terminal segment (Ser 2-Thr 239) of the extracellular domain of human B7-H1 (NP_054862.1) was expressed with a C-terminal polyhistidine tag.

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.
