Background Information
Protein tags are protein or peptide sequences located either on the C- or N- terminal of the target protein, which facilitates one or several of the following characteristics: solubility, detection, purification, localization and expression. The DYKDDDDK(FLAG) peptide has been used extensively as a general tag in expression vectors. This peptide can be expressed and detected with the protein of interest as an amino-terminal or carboxy-terminal fusion. N-terminal DDDDK vectors provide an Ek cleavage site for removal of the fusion tag. The DDDDK peptide is likely to be located on the surface of a fusion protein because of its hydrophilic nature. As a result, the DDDDK peptide is more likely to be accessible to antibodies. A DDDDK-tag can be used in many different assays that require recognition by an antibody, such as western blotting, immunocytochemistry, immunoprecipitation, flow cytometry, protein purification, and in the study of protein-protein interactions, cell ultrastructure, and protein localization and so on. This antibody is a rabbit polyclonal antibody raised against 3xFlag (3xDYKDDDDKT) sequence and recognizes the (1x) and (3x)DYKDDDDK peptide and detects DDDDK-tagged proteins. Anti-FLAG is a registered trademark of Sigma-Aldrich Biotechnology.

Reviews
The reviews below have been submitted by verified Proteintech customers who received an incentive forproviding their feedback.
FH Boyan (Verified Customer) (02-05-2021) | Very strong signal, but with some weak non specific bands.
|
FH Lahiru Chamara (Verified Customer) (11-06-2020) | HEK293 cells were transfected with gene of interested. Primary antibody incubation was performed at 4C for an overnight and Alexa Fluor 488 secondary antibody incubation was performed at room temperature for an hour. Cells were stained with Hoechst for DNA/ nuclei . Images were taken from Zeiss LSM780 microscope.
 |
FH Tongbin (Verified Customer) (08-25-2020) | For western blots, this FLAG antibody is comparable to Sigma's M2 FLAG antibody, which has been the gold standard for FLAG.
|
FH Dipen (Verified Customer) (11-11-2019) | Great antibody for Western blotting. I used it at 1:1000 and got a super strong signal. Will use at a lower concentration next time.
 |
FH Sara (Verified Customer) (10-24-2019) | Works really well for both IP of overexpressed FLAG-tagged proteins and WB!
 |
FH Nikhil (Verified Customer) (10-16-2019) | Flag tagged p53 expressed in H1299 cells.
 |
FH Shivani (Verified Customer) (09-26-2019) | Works better than another brand I had tested.
|
FH Corey (Verified Customer) (08-23-2019) | This antibody has worked well for western blotting as well as immunoprecipitation. The lots have been consistent so far, we will definitely be ordering more.
|
FH Kishor (Verified Customer) (06-23-2019) | Works very good for WB at 1:1000 and IP at 1:200.
|
FH David (Verified Customer) (06-19-2019) | This is working very well for me. I ran out of another brand and got this one because I saw you had it and it was a better value. After testing it in the lab, it works just as well, if not better than the previous one. A very strong signal in my experiments.
