DYKDDDDK-Tag Rabbit Polyclonal Antibody (Binds to same epitope as Sigma's Anti-FLAG(R) M2 Rabbit Polyclonal Antibody) (Alexa Fluor(R) 594 Conjugate)

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).
