OmicsLink™ Anti-D Tag Antibody

Mouse Monoclonal IgG2b

Catalog number

CGAB-DDK-0100 (100 µg)
CGAB-DDK-0050 (50 µg)


Anti-D tag antibody is a purified mouse IgG2b monoclonal antibody that binds to D epitope (DYKDDDDK, also known as FLAG®)-tagged fusion proteins. Anti-D tag antibody can be used to identify and capture fusion proteins by western blots and immunoprecipitation. Immobilized anti-D is also used for affinity purification of D-tag fusion proteins. OmicsLink™ anti-tag antibodies are ideal for use with OmicsLink™ expression-ready ORF cDNA clones.


The OmicsLink™ anti-D tag antibody was produced by immunizing mice with a synthetic peptide (DYKDDDDK) coupled to KLH.


The anti-D tag antibody recognizes over-expressed recombinant proteins containing the D epitope tag (DYKDDDDK) fused to either the N- or C-terminal of targeted proteins in transfected mammalian cells or other expression systems.

Starting dilution recommendations

Optimal working conditions should be determined by the user. General recommendations are western blot at 1:1000;
immunoprecipitation and immunostaining at 1:200.
