EGFR Protein (AA 25-378) (His tag,AVI tag,Biotin)

Catalog No. ABIN4949022

Product Details

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

Protein Type: Recombinant

Biological Activity: Active

Protein Characteristics: AA 25-378

Origin: Human

Source: HEK-293 Cells

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

Application: Functional Studies (Func)

Brand: MABSol®,PrecisionAvi

Sequence: AA 25-378

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 an Avi tag (Avitag™) at the C-terminus, followed by a polyhistidine tag. The protein has a calculated MW of 41.3 kDa. As a result of glycosylation, the protein migrates as 60-70 kDa under reducing (R) condition, and 60-70 kDa under non-reducing (NR) condition (SDS-PAGE).

Purity: >95 % 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: 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. The type III EGF deletion-mutant receptor (EGFRvIII) is the most common mutation and was first identified in primary human glioblastoma tumors, EGFR gene amplification is correlated with the structural rearrangement of the gene. The EGFRvIII gene has an in-frame deletion of 801 base pairs, corresponding to exons 2-7 in the mRNA, resulting in the deletion of amino acids 30-297 in the extracellular domain and the generation of a glycine at the fusion point.
