Product Overview
Recombinant Human ERBB2 protein(NP_001005862.1 )(Thr 23-Ile 450), fused to C-Fc Tag, was expressed in HEK293.
Form
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.
Molecular Mass
The protein has a calculated MW of 73.8 kDa. The protein migrates as 95-100 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Human Her2 (23-450), Fc Tag does not contain Herceptin MAb binding domain.
Storage
For long term storage, the product should be stored at lyophilized state at -20°C or lower.
Please avoid repeated freeze-thaw cycles.
This product is stable after storage at:
-20°C to -70°C for 12 months in lyophilized state;
-70°C for 3 months under sterile conditions after reconstitution.
