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 DNAM1 at 2 μg/ml (100 μl/well) can bind human CD155-Fc with a linear ranger of 0.032-0.8 μg/ml.
Molecular Mass
Recombinant Human CD155/Fc is a disulfide-linked homodimer. The reduced monomer consists of 561 amino acids and predicts a molecular mass of 61.8 kDa. As a result of glycosylation, the rhCD155/Fc monomer migRates as approximately 95-105 kDa band in SDS-PAGE under reducing conditions.
Endotoxin
< 1.0 EU per 1 microgram of protein (determined by LAL method).
Purity
> 97 % by SDS-PAGE.
BACKGROUND
Background
PTH elevates calcium level by dissolving the salts in bone and preventing their renal excretion. Stimulates [1-14C]-2-deoxy-D-glucose (2DG) transport and glycogen synthesis in osteoblastic cells.
