Active Recombinant Human ERBB2 Protein, His-tagged, PE-Labeled

Specification :
| Source : HEK293 | Species : Human | Tag : His | Form : Lyophilized from 0.22 μm filtered solution in PBS, 0.5% BSA, pH7.4. Normally trehalose is added as protectant before lyophilization. | Bio-activity : 5e5 of anti-Her2 CAR-293 cells were stained with 100 μL of 1:25 dilution (4 μL stock solution in 100 μL FACS buffer) of PE-Labeled Human Her2, His Tag and negative control protein respectively. PE signal was used to evaluate the binding activity. | Molecular Mass : This protein carries a polyhistidine tag at the C-terminus.The protein has a calculated MW of 73.0 kDa. | Protein Length : Thr 23 – Thr 652 | 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.
