- SynonymEGFRvIII
- SourceHuman EGFRvIII, His Tag (EGI-H52H4) is expressed from human 293 cells (HEK293). It contains AA Leu 25 - Ser 378 (Accession # NP_001333870.1).Predicted N-terminus: Leu 25Request for sequence
- Molecular Characterization
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 40.5 kDa. The protein migrates as 60-80 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
- EndotoxinLess than 1.0 EU per μg by the LAL method.
- Purity
>95% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
- Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Human EGFRvIII, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
The purity of Human EGFRvIII, His Tag (Cat. No. EGI-H52H4) was more than 90% and the molecular weight of this protein is around 60-75 kDa verified by SEC-MALS.
Immobilized Human EGFRvIII, His Tag (Cat. No. EGI-H52H4) at 1 μg/mL (100 μL/well) can bind Anti-EGFRvIII Antibody , Human IgG1 with a linear range of 0.1-2 ng/mL (QC tested).
2e5 of anti-EGFRvIII CAR-293 cells were stained with 100 μL of 3 μg/mL of Human EGFRvIII, His Tag (Cat. No. EGI-H52H4) and negative control protein respectively, washed and then followed by PE anti-His Tag antibody and analyzed with FACS (Routinely tested).
- BackgroundThe epidermal growth factor receptor (EGFR; ErbB-1; HER1 in humans) is the cell-surface receptor for members of the epidermal growth factor family (EGF-family) of extracellular protein ligands. The epidermal growth factor receptor is a member of the ErbB family of receptors, a subfamily of four closely related receptor tyrosine kinases: EGFR (ErbB-1), HER2/c-neu (ErbB-2), Her 3 (ErbB-3) and Her 4 (ErbB-4). Mutations affecting EGFR expression or activity could result in cancer.The type III EGF deletion-mutant receptor (EGFRvIII) is the most common mutation and was first identified in primary human glioblastoma tumors; EGFR gene amplification is correlated with the structural rearrangement of the gene. The EGFRvIII gene has an in-frame deletion of 801 base pairs, corresponding to exons 2–7 in the mRNA, resulting in the deletion of amino acids 30-297 in the extracellular domain and the generation of a glycine at the fusion point
