Recombinant Human EGFR Protein, Fc-tagged, Alexa Fluor 555 conjugated

• Cat.No.: EGFR-024HAF555
• Product Overview: Alexa Fluor 555 conjugated recombinant human EGFR Fc Chimera(rhEGFR-Fc) Met1-Lys642 (Accession # NP_005219) was expressed in human 293 cells (HEK293).

Specification

• Description: The protein encoded by this gene is a transmembrane glycoprotein that is a member of the protein kinase superfamily. This protein is a receptor for members of the epidermal growth factor family. EGFR is a cell surface protein that binds to epidermal growth factor. Binding of the protein to a ligand induces receptor dimerization and tyrosine autophosphorylation and leads to cell proliferation. Mutations in this gene are associated with lung cancer.

• Source: HEK293
• Species: Human
• Tag: Fc
• Molecular Mass: rhEGFR-Fc is a homodimeric protein and is fused with the Fc region of human IgG1 at the C-terminus. The reduced monomer consists of 860 amino acids and has a calculated molecular mass of 95 kDa. In DTT-reduced SDS-PAGE, protein migrates as 130-140 kDa.
• Protein length: 860
• N-terminal Sequence Analysis: Leu 25
• Endotoxin: < 0.01 ng endotoxin/1 μg rhEGFR-Fc.
• Purity: > 95 % as determined by SDS-PAGE
• Characteristic: Disulfide-linked homodimer
  Labeled with Alexa Fluor 555 via amines
  With an excitation and emission maximum of 555/565 nm, Alexa Fluor 555 can be efficiently excited using a 543 nm He-Ne laser line and detected under standard TRITC/Cy3 filters.
• Storage: Store at -20 centigrade in lyophilized state after receipt. For long term storage, upon reconstitution rhEGFR-Fc should be aliquot and store at -20 centigrade or -8 centigrade centigrade. Avoid repeated freeze-thaw cycles.
• Storage Buffer: Bulk protein in a 0.22 μm filtered solution of PBS, pH 7.4 and delivered as liquid formulation or lyophilized powder. Normally 5-8% trehalose and mannitol are added as protectants before lyophilization.
