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 EGF at 10 μg/ml (100 μl/well) can bind human EGFR with a linear range of 0.64-400 ng/ml.
Molecular Mass
Recombinant Human EGFR/Fc chimera is a homodimeric protein. The reduced monomer consists of 860 amino acids and has a calculated molecular mass of 95 kDa. As a result of glycosylation, Recombinant protein migRates as an approximately 130-140 kDa protein 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
The biological function of streptavidin is not known. Forms a strong non-covalent specific complex with biotin (one molecule of biotin per subunit of streptavidin).
