EGFR Protein (AA 25-645) (His tag,AVI tag,Biotin)

Catalog No. ABIN5674594

Product Details

Target: EGFR (Epidermal Growth Factor Receptor (EGFR))

Protein Type: Recombinant

Biological Activity: Active

Protein Characteristics: AA 25-645

Origin: Human

Source: HEK-293 Cells

Purification tag / Conjugate: This EGFR protein is labelled with His tag,AVI tag,Biotin.

Brand: PrecisionAvi

Sequence: AA 25-645

Specificity: Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

Characteristics: This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag. The protein has a calculated MW of 72.3 kDa. The protein migrates as 100-125 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Purity: >90 % as determined by SDS-PAGE.

Endotoxin Level: Less than 1.0 EU per μg by the LAL method.

Application Details

Comment:

Ready-to-use AvitagTM biotinylated protein:
The product is exclusively produced using the AvitagTM technology. Briefly, a unique 15 amino acid peptide, the Avi tag, is introduced into the recombinant protein during expression vector construction. The single lysine residue in the Avi tag is enzymatically biotinylated by the E. Coli biotin ligase BirA.

This single-point enzymatic labeling technique brings many advantages for commonly used binding assays. The biotinylation happens on the lysine residue of Avi tag, and therefore does NOT interfere with the target protein's natural binding activities. In addition, when immobilized on an avidin-coated surface, the protein orientation is uniform because the position of the Avi tag in the protein is precisely controlled.

Target Details

Target: EGFR (Epidermal Growth Factor Receptor (EGFR))

Alternative Name: EGF R (EGFR Products)

Background: The epidermal growth factor receptor (EGFR, ErbB-1, HER1 in humans) is the cell-surface receptor for members of the epidermal growth factor family (EGF-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 (ErbB-1), HER2/c-neu (ErbB-2), Her 3 (ErbB-3) and Her 4 (ErbB-4). Mutations affecting EGFR expression or activity could result in cancer.
