3x DYKDDDDK – tag peptide

3x DYKDDDDK peptide,also called 3x FLAG peptide,is a 23 aa length peptide used for the competitive elution of DYKDDDDK-tag fusion proteins (with excess of free 3x DYKDDDDK peptide) under non-denaturing conditions,especially when a DYKDDDDK-tagged protein is sensitive to low pH. Involvement in COVID-19 disease Some recombinant proteins,such as Spike glycoprotein and ACE2 are frequently produced using the FLAG-tag system. In order to elute such proteins purified by affinity,sb-PEPTIDE provides DYKDDDDK peptide and 3x DYKDDDDK peptide. To help your research for COVID-19 disease,we can also provide you with premium quality peptide libraries containing SARS-CoV-2 proteins. Our expertise make us able to synthesize glycopeptides and phosphopeptides to be close from the real content of these peptides.
