Species | Human |
Tag | C-His-Avi |
Expression Systems | Expi293 |
Keywords | Human; C-His-Avi; Expi293 |
Synonyms | ErbB; EC 2.7.10; EC 2.7.10.1; EGFR; mENA; LEGFR; ERBB; ERBB1; HER1; PIG61; NISBD2 |
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. |
Source | Recombinant Human EGFRVIII Protein is expressed from Expi293 with His tag and Avi tag at the N-terminal. It contains Leu25-Ser378. |
Molecular Weight | The protein has a predicted MW of 41.6 kDa. Due to glycosylation, the protein migrates to 68-80 kDa based on Tris-Bis PAGE result. |
Endotoxin | Less than 1 EU per μg by the LAL method. |
Purity | >95% as determined by Tris-Bis PAGE. >95% as determined by HPLC. |
Formulation | Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. |
Reconstitution | Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
Storage | -20 to -80℃ for 12 months as supplied from the date of receipt. -20 to -80℃ for 3-6 months in an unopened state after reconstitution. 2-8℃ for 2-7 days after reconstitution. |
Notes | Recommend to aliquot the protein into smaller quantities for optimal storage. Please avoid freeze-thaw cycles. |
