| The epidermal growth factor receptor is a transmembrane protein that is a receptor for members of the epidermal growth factor 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, HER2/neu, Her 3 and Her 4. Receptor tyrosine kinase binding ligands of the EGF family and activating several signaling cascades to convert extracellular cues into appropriate cellular responses. |
| Recombinant Biotinylated Human EGFR/HER1 Protein is expressed from Expi293 with His tag and Avi tag at the C-terminal. It contains Leu25-Ser645. |

| Less than 1EU per ug by the LAL method. |
|
| Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as a protectant before lyophilization. |
|
| Reconstituted protein stable at -80 C for 12 months, 4 C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. |
|
| Shipped at ambient temperature. |
|
| Centrifuge tubes before opening. Reconstituting to a concentration of more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water. |
