Anti-E-tag Antibody, Rabbit Polyclonal Images

Immunofluorescence staining of E-Tag in Hela cells, transfected with pSTEP2-Etag-GFERh (Figure A), pSTEP2-his-Etag-GFER (Figure B), pSTEP2-his-GFER-Etag (Figure C), pSTEP2-Etag-GSTT2h (Figure D),pSTEP2-his-Etag-GSTT2 (Figure E) and pSTEP2-his-GSTT2-Etag (Figure F). Cells were fixed with 4% PFA, permeabilzed with 0.3% Triton X-100 in PBS, blocked with 10% serum, and incubated with rabbit anti-E-Tag polyclonal antibody at 37℃ 1 hour. Then cells were stained with the Alexa Fluor® 488-conjugated Goat Anti-rabbit IgG secondary antibody (green) and counterstained with DAPI (blue).

E-tag Background Information

The E Tag is a 13-peptide epitope commonly fused to the N- or C- termini of recombinantly expressed proteins. The E Tag (amino acid sequence: GAPVPYPDPLEPR) is a popular epitope tag that can be engineered to a protein through recombinant DNA technology. The E tag contains 13 amino acids and has a molecular weight of 1.4 kDa. Antibodies to the E-tag may be a useful tool in the detection and investigation of E-tagged proteins. Anti-E Tag antibodies facilitate the detection, isolation, and purification of E-tagged target proteins without a protein-specific antibody or probe. Epitope tags are useful for the labeling and detection of proteins using immunoblotting, immunoprecipitation, and immunostaining techniques. Because of their small size, they are unlikely to affect the tagged protein’s biochemical properties.
