Bacterial and mammalian expression vectors, or expression constructs, are circularized DNA transfection plasmids that are commonly used to overexpress recombinant proteins of interest. The FLAG® Expression System is an established way to express, purify and detect recombinant fusion proteins.
How do you FLAG-tag a protein?
FLAG-tag, or FLAG octapeptide, or FLAG epitope, is a polypeptide protein tag that can be added to a protein using recombinant DNA technology, having the sequence motif DYKDDDDK (where D=aspartic acid, Y=tyrosine, and K=lysine).
What are myc and flag?
FLAG tag Like the Myc tag, the FLAG tag is a popular short peptide tag (DYKDDDDK) used in recombinant DNA technology and can be used for affinity chromatography and for isolating protein complexes with multiple subunits.FLAG tag Like the Myc tagMyc tagA myc tag is a polypeptide protein tag derived from the c-myc gene product that can be added to a protein using recombinant DNA technology. It can be used for affinity chromatography, then used to separate recombinant, overexpressed protein from wild type protein expressed by the host organism.https://en.wikipedia.org › wiki › Myc-tagMyc-tag - Wikipedia, the FLAG tag is a popular short peptide tag (DYKDDDDK) used in recombinant DNA technology and can be used for affinity chromatography and for isolating protein complexes with multiple subunits.10 Jun 2014
What is a flag HA tag?
The FLAG® HA tandem epitope system consists of small epitopes tags that are not eukaryotic derived. The hydrophilic character of the FLAG® HA peptide increases the likelihood that the dual epitope will be located on the surface of the fusion protein where it is accessible for the antibody-antigen interaction.
What is a Flag antibody?
The FLAG tag (peptide sequence DYKDDDDK) is a short, hydrophilic protein tag commonly used in conjunction with antibodies in protein pull-downs to study protein–protein interactions. We offer quality antibodies specific to FLAG tag that can be used in a variety of research needs.

What is Flag in Western blot?
Flag is a tag (small peptide) that you add to your protein (either to the N or C-terminus) to facilitate the detection or pull down of your protein.16 Feb 2017
How big is a V5 tag?
There are two sizes of the V5 tag ranging from 9–14 amino acids, although the longer tag is usually used.
What is an epitope tag?
Epitope tagging is a method of expressing proteins whereby an epitope for a specific monoclonal antibody is fused to a target protein using recombinant DNA techniques. The fusion gene is cloned into an appropriate expression vector for the experimental cell type and host cells are transfected.
What is T7 tag?
The T7 tag is an 11 amino acid peptide encoded in the leader sequence of T7 bacteriophage gene10. The T7 tag serves as a tag in many expression vectors including the pET system that is based on the very efficient T7 RNA polymerase expression system.The T7 tag is an 11 amino acid peptide encoded in the leader sequence of T7 bacteriophageT7 bacteriophageBacteriophage T7 (or the T7 phage) is a bacteriophage, a virus that infects bacteria. Bacteriophage T7 has a lytic life cycle, meaning that it destroys the cell it infects.https://en.wikipedia.org › wiki › T7_phageT7 phage - Wikipedia gene10.

What is Flag in molecular biology?
FLAG-tag, or FLAG octapeptide, or FLAG epitope, is a polypeptide protein tag that can be added to a protein using recombinant DNA technology, having the sequence motif DYKDDDDK (where D=aspartic acid, Y=tyrosine, and K=lysine). A FLAG-tag can be used in many different assays that require recognition by an antibody.
What is the size of the flag protein?
about 1 kDa
What is FLAG peptide used for?
Typically the Flag® tag is used for protein purification from mammalian expression systems or general immunostaining and immunoprecipitation assays.
