    Product Information

    Product Description

    This Cell Signaling Technology® antibody is the biotinylated version of the unconjugated DYKDDDDK Tag (D6W5B) Rabbit Monoclonal Antibody (Binds to same epitope as Sigma-Aldrich Anti-FLAG M2 antibody) #14793 and is expected to exhibit the same species cross-reactivity. The concentration of the biotinylated antibody is 500 ug/ml. Peptide ELISA data were generated using the biotinylated antibody. Western blot data were generated using the unconjugated antibody.

    Product Usage Information

    Biotinylated antibodies are ideal for immunoassay technologies and high-throughput ELISA platforms that require antibody pairs where both antibodies are from the same host. Platforms utilizing biotinylated antibodies include, but are not limited to, MSD, xMAP, Quanterix Simoa, AlphaLISA, AlphaScreen, HTRF, LANCE, and TR-FRET.

    Optimal dilutions/working concentrations should be determined by the end user. Please contact us if you require the antibody clone biotinylated at a different concentration, a carrier-free formulation, or a more customized packaging solution.

    Storage

    Supplied in 140 mM NaCl, 3 mM KCl, 10 mM sodium phosphate (pH 7.4) dibasic, 2 mM potassium phosphate monobasic, 2 mg/mL BSA, and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

    Protocol

    Specificity / Sensitivity

    DYKDDDDK Tag (D6W5B) Rabbit Monoclonal Antibody (Binds to same epitope as Sigma-Aldrich Anti-FLAG M2 antibody) (Biotinylated) detects exogenously expressed DYKDDDDK proteins in cells. This antibody recognizes the DYKDDDDK peptide, which is the same epitope recognized by Sigma's Anti-FLAG antibodies, fused to either the amino terminus or carboxy terminus of the target protein.

    Species Reactivity:

    All Species Expected

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic DYKDDDDK peptide.

    Background

    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.

    The DYKDDDDK peptide has been used extensively as a general epitope tag in expression vectors. This peptide can be expressed and detected with the protein of interest as an amino-terminal or carboxy-terminal fusion (1).
