The DYKDDDDK tag, commonly referred to as Sigma®'s FLAG® Tag, is often used as a protein modification in order to simplify the labeling and detection of proteins.This unique amino acid sequence allows for specific antibody detection in western blotting, immunoprecipitation, and immunostaining techniques.Due to the short sequence, this modification is not likely to affect the structure or function of the modified proteins.

Does a relatively low pH such as 4.5 dissociate the L5 antibody from the resin?
pH4.5 should not diassociate the antibody from the resin. But this pH could affect the binding of the FLAG-tagged target to the L5 antibody.
