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 CD55 at 2 μg/ml (100 μl/well) can bind human CD97 with a linear ranger of 1.28-32 ng/ml.
Molecular Mass
Recombinant Human CD97/Fc chimera is a disulfide-linked homodimeric protein. The reduced monomer consists of 619 amino acids and predictes a molecular mass of 68.2 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh CD97/Fc monomer is approximately 100-110 kDa due to glycosylation.
Endotoxin
< 1.0 EU per 1 microgram of protein (determined by LAL method).
Purity
> 90 % by SDS-PAGE.
BACKGROUND
Background
Receptor potentially involved in both adhesion and signaling processes early after leukocyte activation. Plays an essential role in leukocyte migration (By similarity).
