Lyophilized from sterile PBS, pH 7.4, 5 % trehalose and 5 % mannitol.
Bio-activity
Measured by its binding ability in a functional ELISA. Immobilized human PD-1 at 10 μg/ml (100 μl/well) can bind recombinant human B7-H1 / PD-L1 / Fc chimera with a linear range of 0.02-0.4 μg/ml.
Molecular Mass
RecombinantHuman 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.
Endotoxin
< 1.0 EU per 1 microgram of protein (determined by LAL method).
Purity
> 95 % by SDS-PAGE.
Storage
In lyophilized state for 1 year (4°C); After reconstitution under sterile conditions for 3 months (-70°C). Avoid repeated freeze/thaw cycles.
Reconstitution
Reconstitute in sterile distilled water to a concentration of 0.1-1.0 mg/mL.

Background
Induces cartilage and bone formation. Also act in mesoderm induction, tooth development, limb formation and fracture repair. Acts in concert with PTHLH/PTHRP to stimulate ductal outgrowth during embryonic mammary development and to inhibit hair follicle induction.
