Active Recombinant Human EGFR protein, His/Avi-tagged, Biotinylated

Specification :
| Source : HEK293 | Species : Human | Tag : His/Avi | Form : Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization. | Bio-activity : Immobilized Cetuximab at 2 μg/mL (100 μL/well) can bind Biotinylated Human EGF R, His,Avitag with a linear range of 2-6 ng/mL. | Molecular Mass : The protein has a calculated MW of 72.3 kDa. The protein migrates as 90-125 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation. | Protein Length : Leu 25 – Ser 645 | Endotoxin : Less than 1.0 EU per μg by the LAL method. | Purity : >90% as determined by SDS-PAGE.>90% as determined by SEC-MALS. | Storage : For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.Please avoid repeated freeze-thaw cycles.This product is stable after storage at:-20 centigrade to -70 centigrade for 12 months in lyophilized state;-70 centigrade 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℃ before opening to recover the entire contents.
