Human EGFR/HER1 Protein

COA MSDS
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 His tag at the C-terminus.
It contains Leu25-Ser645 [Accession | P00533-1].

分子量大小(Molecular Weight)

The protein has a predicted MW of 70.19 kDa. Due to glycosylation, the protein migrates to 80-110 kDa based on Bis-Tris PAGE result.

纯度(Purity)

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

内毒素(Endotoxin)

Less than 0.1 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)

Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.

存储(Storage)

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

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)

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