Predicted Molecular Weight
The recombinant human ErbB2/Fc chimera is a disulfide-linked homodimeric protein generated by proteolytic removal of the signal peptide. The monomer comprises 868 amino acids and has a calculated molecular mass of 96.1 kDa. As a result of glycosylation, the monomer migrates as an approximately 130-140 kDa protein in SDS-PAGE under reducing conditions.
Expression System
HEK 293 Cells
Source Species
Human
Purification
> 90 % as determined by SDS-PAGE
Bio-Activity
Measured by its binding ability in a functional ELISA.Immobilized human ErbB2 at 2.5 µg/ml can bind Herceptin with a linear range of 3.2-80 ng/ml. Measured by its ability to block anti-ErbB2 mediated inhibition of BT474 human breast ductal carcinoma cell proliferation. The ED50 for this effect is 0.5-3 µg/mL in the presence of 0.6 µg/mL Anti-ErbB2/Her2 Monoclonal Antibody.
Endotoxin
Less than 1.0 EU/µg protein (determined by LAL method).
Presentation
Lyophilized from sterile PBS, pH 7.4, 5% trehalose, 5% mannitol and 0.01% Tween80
Reconstitution
Reconstitute in 400ul of sterile water to a concentration of 0.25mg/ml
Storage
Aliquot and store at -20°C to -80°C for one year. Avoid repeated freeze-thaw cycles.
Restrictions
For research use only. Intended for use by laboratory professionals.
