EGFR Protein, Human, Recombinant (Isoform vIII, His & Avi), Biotinylated

As a member of the epidermal growth factor receptor (EGFR) family, EGFR protein is type I transmembrane glycoprotein that binds a subset of EGF family ligands including EGF, amphiregulin, TGF-α, betacellulin, etc. EGFR protein plays a crucial role in signaling pathway in the regulation of cell proliferation, survival and differentiation. Binding of a ligand induces EGFR protein homo- or heterodimerization, the subsequent tyrosine autophosphorylation and initiates various down stream pathways (MAPK, PI3K/PKB and STAT). In addition, EGFR signaling also has been shown to exert action on carcinogenesis and disease progression, and thus EGFR protein is proposed as a target for cancer therapy currently.Cancer ImmunotherapyImmune CheckpointImmunotherapyTargeted Therapy

Description

Species	Human
Expression System	HEK293
Tag	His,AVI
Accession Number	NP_001333870.1
Synonyms	PIG61, ERBB1, ERBB, NISBD2, epidermal growth factor receptor, HER1, mENA
Construction	A DNA sequence encoding the human EGFR (NP_001333870.1) (Met1-Ser378) was expressed with a c-terminal polyhistidine tagged AVI tag at the C-terminus. The expressed protein was biotinylated in vivo by the Biotin-Protein ligase (BirA enzyme) which is co-expressed.
Protein Purity	> 95 % as determined by SDS-PAGE. > 95 % as determined by SEC-HPLC.
Molecular Weight	Approxiamtely 41.90 kDa

Endotoxin	< 1.0 EU per μg protein as determined by the LAL method.
Formulation	Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0. 01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.
Reconstitution	A hardcopy of datasheet with reconstitution instructions is sent along with the products. Please refer to it for detailed information.
Stability & Storage	Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Shipping	In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
