Epitope tagging is a widely accepted technique that fuses an epitope peptide to a protein as a marker for gene expression. With this technique, the gene expression can be easily monitored on Western blotting, immunoprecipitation and immunofluorescence utilizing an antibody that recognizes such an epitope. Amino acid sequences that are widely used for the epitope tagging are as follows, YPYDVPDYA (HA-Tag), EQKLISEEDL (Myc-Tag) and YTDIEMNRLGK (VSV-G-Tag), which correspond to the partial peptide of Influenza hemagglutinin protein, Human c-myc gene product and Vesicular stomatitis virus glycoprotein respectively.Synonyms: c-myc tag, myc tag, myc-tag
