Recombinant Human HER1/ERBB1/EGFR Protein (RP01029)

Overview

Product name	Recombinant Human HER1/ERBB1/EGFR Protein
Catalog No.	RP01029
Description	Recombinant Human HER1/ERBB1/EGFR Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Met1-Ser645) of human EGFR (Accession #NP_005219.2. ) fused with an Fc, 6×His tag at the C-terminus.
Bio-Activity	Measured by its binding ability in a functional ELISA. Immobilized recombinant human EGF at 0.5 μg/mL (100 μL/well) can bind Rrecombinant human EGFR with a linear range of 0.3-2.5 μg/mL.
Purity	> 90% by SDS-PAGE.
Endotoxin	< 0.1 EU/μg of the protein by LAL method.
Formulation	Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation.
Species	Human
Calculated MW	97.64 kDa

The EGFR (epidermal growth factor receptor) subfamily of receptor tyrosine kinases comprises four members: EGFR (also known as HER-1, ErbB1, or ErbB), ErbB2 (Neu, HER-2), ErbB3 (HER-3), and ErbB4 (HER-4). EGFR protein is type I transmembrane glycoprotein that binds a subset of EGF family ligands including EGF, amphiregulin, TGF-α, betacellulin, etc.The human EGFR cDNA encodes a 1210 amino acid (aa) precursor with a 24 aa signal peptide, a 621 aa extracellular domain (ECD), a 23 aa transmembrane segment, and a 542 aa cytoplasmic domain. EGFR signaling has been shown to exert action on carcinogenesis and disease progression, and thus EGFR protein is proposed as a target for cancer therapy currently, which is overexpressed in a wide variety of tumors and is the target of several anti-cancer drugs.

Usage guide

Storage	Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
Reconstitution	Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
