FLAG peptide TFA 

FLAG peptide TFA is the TFA salt form of FLAG peptide (HY-P0223). FLAG peptide TFA is a multifunctional fusion tag for the purification of recombinant proteins. FLAG peptide TFA maintances the natural folding of its fusing proteins. FLAG peptide TFA can be removed by enterokinase, and eluted under non-denaturing conditions^[1].
