Product Description |
Recombinant Biotinylated Human EGFRVIII Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Leu25-Ser378. |
Product Background |
The epidermal growth factor receptor (EGFR) is overexpressed in a variety of human epithelial tumors, often as a consequence of gene amplification. Tumors with EGFR gene amplification frequently contain EGFR gene rearrangements, with the most common extracellular domain mutation being EGFRvIII. This mutation leads to a deletion of exons 2-7 of the EGFR gene and renders the mutant receptor incapable of binding any known ligand. |

Amino Acid Range |
Leu25-Ser378 |
Molecular Weight |
The protein has a predicted MW of 41.6 kDa. Due to glycosylation, the protein migrates to 60-78 kDa based on Bis-Tris PAGE result. |
Activity |
Immobilized Biotinylated Human EGFRVIII, His Tag at 0.5ug/ml (100ul/Well) on streptavidin (5ug/ml) precoated plate. Dose response curve for Anti-EGFR VIII Anitibody, hFc Tag with the EC50 of 14.7ng/ml determined by ELISA (QC Test). See testing image for detail. |

Formulation |
Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water. |

Biotinylated Human EGFRVIII on Bis-Tris PAGE under reduced condition. The purity is greater than 95%. |
|
|
Use Biotinylated Human EGFRVIII, His Tag protein to detect the expression rate of Anti-EGFRVIII-CAR positive cell. 293T cells and anti-EGFRVIII CAR-293T cells were incubated with Biotinylated human EGFR VIII-His Tag. Non-transfected 293T cells and Biotinylated protein control were used as negative control. SA-PE was used to evaluate the binding activity of Biotinylated Human EGFR VIII. |
