Peptide xxxDDDDK conjugated to KLH. xxx represents random amino acids. This sequence represents the Enterokinase Cleavage Site.
Epitope tags provide a method to localize gene products in a variety of cell types, study the topology of proteins and protein complexes, identify associated proteins, and characterize newly identified, low abundance or poorly immunogenic proteins when protein specific antibodies are not available. Tagging with xxxDDDDK may be done at the N-terminus, N-terminus preceded by a methionine residue, C-terminus, and in internal positions of the target protein. The small size of the epitope tag and its high hydrophilicity tend to decrease the possibility of interference with protein expression, proteolytic maturation, antigenicity and function. The enterokinase cleavage site allows it to be completely removed from the purified fusion proteins.
FLAG® is a registered trade mark of Sigma Aldrich Biotechnology LP.

Our Abpromise guarantee covers the use of ab1162 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||Use a concentration of 0.2 - 1 µg/ml.
Antibody was analyzed by western blot using various amino-terminal and carboxy-terminal DDDDK fusion proteins and Invitrogen Positope" R900-40. A 1/5000 dilution gave bands against 0.1, 1.0 and 10 ng of the fusion proteins and 100 ng and 25 ng of the Positope.
|ICC/IF||Use at an assay dependent concentration.|
|ELISA||Use a concentration of 1 - 5 µg/ml.
As coating antibody in sELISA.
|IP||1/40. PubMed: 25419851|

Immunofluorescent analysis of A293 cells labeling FLAG®-VPS35 with ab1162 at 10 μg/ml. The nuclear counter stain is DAPI (blue).
ab1162 staining DDDDK tag in hTERT-RPE1 by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with Paraformaldehyde, permeabilized with Saponin and blocked with 0.02% BSA for 20 minutes at 18°C. Samples were incubated with primary antibody (1/100) for 45 minutes at 18°C. A Cy3®-conjugated Donkey anti-rabbit polyclonal was used as the secondary antibody.
