Flag tag Rabbit anti-Tag, Polyclonal, Proteintech

Description

This antibody is a rabbit polyclonal antibody raised against the 3xDYKDDDDKT sequence and recognizes the (1x) and (3x)DYKDDDDK peptide and detects DDDDK-tagged proteins.

DDK (FLAG-tag, FLAG octapeptide, FLAG epitope) is a polypeptide protein tag that can be added to a protein using recombit DNA technology, having the sequence motif DYKDDDDK (where D=aspartic acid, Y=tyrosine, and K=lysine). It is an artificial antigen to which specific, high affinity monoclonal antibodies have been developed and hence can be used for protein purification by affinity chromatography and also can be used for locating proteins within living cells. It has been used to separate recombit, overexpressed protein from wild-type protein expressed by the host organism. It can also be used in the isolation of protein complexes with multiple subunits, because its mild purification procedure tends not to disrupt such complexes. It has been used to obtain proteins of sufficient purity and quality to carry out 3D structure determination by x-ray crystallography.
