Active Recombinant Human ERBB2 protein, His-tagged

Species :	Human
Source :	HEK293
Tag :	His
Protein Length :	23-510 aa
Form :	Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
Bio-activity :	Immobilized Human Her2 (23-510), His Tag at 1 μg/mL (100 μL/well) can bind Pertuzumab Biosimilar with a linear range of 0.1-4 ng/mL.Immobilized Human Her2 (23-510), His Tag at 1 μg/mL (100 μL/well) can bind Bispecific Antibody (Her2 × Her3) with a linear range of 0.2-3 ng/mL.
Molecular Mass :	This protein carries a polyhistidine tag at the C-terminus.The protein has a calculated MW of 55.6 kDa. The protein migrates as 65-75 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Endotoxin :	Less than 1.0 EU per μg by the LAL method.
Purity :	>95% as determined by SDS-PAGE.
Storage :	For long term, the product should be stored at lyophilized state at -20°C or lower.Please protect from light and avoid repeated freeze-thaw cycles.This product is stable after at: -20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution.
Reconstitution :	It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
