Lyophilized from sterile PBS, pH 7.4, 5 % trehalose and 5 % mannitol.
Bio-activity
Measured by its binding ability in a functional ELISA. Immobilized recombinant human CD40 at 2 μg/ml (100 μl/well) can bind biotinylated human CD40L with a linear range of 15.6-500 ng/ml.
Molecular Mass
Recombinant Human CD40 comprises 184 amino acids with a predicted molecular mass of 20.7 kDa. As a result of glycosylation, rhCD40 migRates as an approximately 32 kDa band in SDS-PAGE under reducing conditions.
Endotoxin
< 1.0 EU per 1 microgram of protein (determined by LAL method).
Purity
> 98 % by SDS-PAGE.
BACKGROUND
Background
Hirudin is a potent thrombin-specific protease inhibitor. It forms a stable non-covalent complex with alpha-thrombin, thereby abolishing its ability to cleave fibrinogen.
