Background: DYKDDDDK Epitope Tag

Fusion proteins, in which a known peptide such as a His-Tag, GST-Tag, or DYKDDDDK (FLAG(R)) is cloned with the target of interest, were developed to simplify protein isolation. Since specific antibodies may not be available against the protein of interest, epitope tag antibodies are commonly used to detect protein expression.

The epitope tag, DYKDDDDK, is comprised of an eight amino acid sequence derived from the gene-10 product from bacteriophage T7 and contains an enterokinase-cleavage site (1). Its hydrophilic nature and short peptide sequence reduce possible interference with protein expression, post-translational modifications, protein interactions, and protein function (2). The DYKDDDDK (FLAG(R)) epitope tag can either be fused to the N-terminus, C-terminus, or placed at an internal position of the target protein, facilitating characterization of the protein of interest using immunodetection methods. Compared to the standard DYKDDDDK epitope tag antibody, the rat monoclonal DYKDDDDK Epitope Tag antibody (clone L5) is 2-8 times more sensitive (3).

FAQs for DYKDDDDK Epitope Tag Antibody [Agarose]

Showing  1 - 5 of 6 FAQs Showing All

  • Q: Are the FLAG Tag antibodies validated in Simple Western?

    A: Yes, we offer 3 FLAG Tag antibodies that have been tested in Simple Western: NBP1-71705, NBP1-97410, and MAB8529.

  • Q: Do FLAG Tag antibodies comes in lyophilized form?

    A: The following FLAG Tag antibodies come in lyophilized form: NBP1-97393, NBP1-97401, NBP1-97399, NBP1-97400, and NBP1-97402.

  • Q: What is the immunogen sequence of this FLAG Tag antibody? 

    A: This antibody was made to a ECS enterokinase cleavage site (xxxDDDDK) conjugated to KLH.  

  • Q: What the theoretical molecular weight for FLAG Tag antibodies?

    A: The TMW for DYKDDDDK epitope FLAG Tag is approximately 1.01 kDa.

  • Q: Will FLAG Tag antibodies detect internal FLAG tags? My FLAG sequence is sandwiched between two other protein sequences.

    A: 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.

  • Q: Will FLAG Tag antibodies recognize FLAG at the C-terminal end?

    A: Yes, FLAG Tag antibodies can recognize FLAG-tag at both the N- or C-terminal.

  • Q: Are the FLAG Tag antibodies validated in Simple Western?
