Product Description |
Recombinant Human EGFR/HER1 Protein is expressed from HEK293 with hFc tag at the C-Terminus.; It contains Leu25-Ser645. |
Product Background |
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. |

Accession |
|
Species |
Human |
Biotinylated |
no |
Amino Acid Range |
Leu25-Ser645 |
Molecular Weight |
The protein has a predicted MW of 95.2 kDa. Due to glycosylation, the protein migrates to 110-140 kDa based on Bis-Tris PAGE result. |
Activity |
Immobilized Human EGF, No Tag at 5 ug/ml (100 ul/well) on the plate. Dose response curve for Human EGFR, hFc Tag with the EC50 of 0.44 ug/ml determined by ELISA. See testing image for detail. |
Product Tag |
C-hFc |
Express System |
HEK293 |
Purity |
> 95% as determined by Bis-Tris PAGE; > 95% as determined by HPLC |
Endotoxin |
Less than 1 EU per ug by the LAL method. |
Form |
Lyophilized |
Shipping |
Shipped at ambient temperature. |
Formulation |
Lyophilized from 0.22 um 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. |
Stability And Storage |
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. |
