Design Notes
In order to prepare a ready-to-use FLAG-tag which can be easily added to other BioBrick™ Standard Biological Parts (for separation, recognition, etc.), a FLAG-tag encoding sequence flanked by standard BioBrick™ prefix (EcoRI, XbaI) and suffix (SpeI, PstI) is designed and ligated into standard DNA-shipping plasmid backbone pSB1C3. The DNA sequence of the FLAG-tag is as follows: 5’ gactacaaggatgacgacgacaag 3’; while the corresponding peptide sequence would be as follow: N-DYKDDDDK-C.
FLAG-tag is a polypeptide protein tag commonly used in molecular biology, particularly recombinant DNA technology. It can be tagged to the N-terminal or C-terminal of a protein coding sequence; it can also be added between two domains of a chimeric protein, giving that that the insertion of FLAG-tag will not affect the expected function of the polypeptide. FLAG-tag is used in affinity chromatography to separate or detect recombinant, overexpressed protein from wild-type protein; it can also be used in cellular localization studies by immunofluorescence or detection by SDS-PAGE protein electrophoresis.
