Immunoprecipitation of DYKDDDDK (FLAG epitope) Tagged Proteins—Anti-DYKDDDDK Beads

Anti-DYKDDDDK Beads consist of a monoclonal anti-DYKDDDDK antibody (which recognizes the FLAG epitope), crosslinked to agarose beads. These beads are used to purify or immunoprecipitate DYKDDDDK-tagged or FLAG-tagged fusion proteins from cell lysates. Clontech’s Anti-DYKDDDDK Beads and Immunoprecipitation Buffer Set can be purchased separately to make a complete Co-IP kit for purification of FLAG-tagged proteins.

The Immunoprecipitation Buffer Set contains a highly optimized mix of buffers which provide extremely low background and are recommended for use with the Anti-DYKDDDDK Beads.
