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

• Cat.No.: EGFR-1258H
• Product Overview: Recombinant Human EGFR Protein (25-378aa), was expressed in HEK293 with C-terminal His tag, Avi tag and biotinylated conjugate.

Specification

• Species: Human
• Source: HEK293
• Tag: Avi&His
• Protein Length: 25-378 aa
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
• Bio-activity: Immobilized Biotinylated Human EGFRvIII, His,Avitag at 1 μg/mL (100 μL/well) on streptavidin precoated (0.5 μg/well) plate can bind Anti-EGFRvIII Antibody, Human IgG1 with a linear range of 0.1-3 ng/mL.Immobilized CetuxiMab at 1 μg/mL (100 μL/well) can bind Biotinylated Human EGFRvIII, His,Avitag with a linear range of 0.2-2 ng/mL.
• Molecular Mass: This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™)The protein has a calculated MW of 42.2 kDa. The protein migrates as 60-90 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. >90% as determined by SEC-MALS.
• 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.
• Conjugation: Biotin
