DYKDDDDK Epitope Tag Antibody (29E4.G7) [HRP] Summary

This antibody was produced in mice by repeated immunizations with a synthetic peptide corresponding to the FLAG epitope tag peptide DYKDDDDK (Asp-Tyr-Lys-Asp-Asp-Asp-Asp-Lys) conjugated to KLH using maleimide. Residues of glycine and cysteine were added
The purified antibody is directed against the motif and is useful in determining its presence in various assays where the epitope tag is present at either the amino or carboxy terminus of recombinant proteins. This monoclonal tag antibody detects over-expressed proteins containing the epitope tag. In western blotting of bacterial extracts, the antibody does not cross-react with endogenous proteins.

Application Notes
This antibody is optimally suited for monitoring the expression of FLAG tagged fusion proteins. As such, this antibody can be used - identify fusion proteins containing the FLAG epitope. The antibody recognizes the epitope tag fused - either the amino- or carboxy- termini of targeted proteins. The epitope tag peptide sequence was first derived from the 11-amino-acid leader peptide of the gene-10 product from bacteriophage T7. DYKDDDDK is the most commonly used hydrophilic octapeptide tag.

FAQs for DYKDDDDK Epitope Tag Antibody (NBP1-97393). (Showing 1 - 7 of 7 FAQ).

  1. Are the FLAG Tag antibodies validated in Simple Western?
    • Yes, we offer a 2 FLAG Tag antibodies that have been tested in Simple Western: NB600-345 and NBP1-71705.
  2. Does FLAG Tag antibodies comes in lyophilized form?
    • The following FLAG Tag antibodies come in lyophilized form: NBP1-97401, NBP1-97399, NBP1-97400, NBP1-97402.
  3. What the theoretical molecular weight for FLAG Tag antibodies?
    • The TMW of FLAG Tag antibodies is approximately 150 kDa.
  4. Will FLAG Tag antibodies detect internal FLAG tags? My FLAG sequence is sandwiched between two other protein sequences.
    • If you are applying your sample(s) to SDS-PAGE, under reducing condition and follow by Western Blot, DYKDDDDK epitope tag antibodies should be able to detect the tag region located internally. However, it depends on the property of your chimeric protein and if your tag is in the hydrophobic or hydrophilic region. Although DYKDDDDK is very hydrophilic, it may not be exposed to the surface if embedded deeply inside the protein with a high content of hydrophobic amino acids with or without covalently-linked modifications such as lipid moieties.
  5. Will FLAG Tag antibodies recognizes FLAG at the C-terminal end?
    • Yes, FLAG Tag antibodies can recognize FLAG-tag at both the N- or C-terminal.
  6. Hello. We are planning to promote DYKDDDDK Antibodies in our February 2013 newsletter. Thus, we would like to check toxicity of a few products. Could you let us know whether these are lyophilized form?
    • NBP1-97393 does not come in lyophilized form.
  7. What is the immunogen sequence of this FLAG Tag antibody?
    • A synthetic peptide (Asp-Tyr-Lys-Asp-Asp-Asp-Asp-Lys) corresponding to the FLAG epitope tag peptide DYKDDDDK, conjugated to KLH.
