Human EGFR/HER1 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Human EGFR/HER1 Protein is expressed from HEK293 with hFc tag at the C-Terminus.
It contains Leu25-Ser645 [Accession | P00533].

分子量大小(Molecular Weight)

The protein has a predicted MW of 95.2 kDa. Due to glycosylation, the protein migrates to 110-140 kDa based on Tris-Bis PAGE result.

纯度(Purity)

> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC

内毒素(Endotoxin)

Less than 1 EU per μg by the LAL method.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

重构方法(Reconstitution)

Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

存储(Storage)

-20 to -80°C for 12 months as supplied from date of receipt.; -80°C for 3-6 months after reconstitution.; 2-8°C for 2-7 days after reconstitution.; Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

产品数据(Assay Data)
Tris-Bis PAGE

Human EGFR on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.

SEC-HPLC

The purity of Human EGFR is greater than 95% as determined by SEC-HPLC.

ELISA Data

Immobilized Human EGF, No Tag at 5 μg/ml (100 μl/well) on the plate. Dose response curve for Human EGFR, hFc Tag with the EC50 of 0.44 μg/ml determined by ELISA.

背景(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.

分子别名(Synonyms)

ErbB; EC 2.7.10; EC 2.7.10.1; EGFR; mENA; LEGFR; ERBB; ERBB1; HER1; PIG61; NISBD2

Note: HPLC results always come from liquid protein, due to absorption peak interference of trehalose in lyophilized powder.
