c-Myc Epitope (Myc)

A 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. It can also be used in the isolation of protein complexes with multiple subunits. A myc tag can be used in many different assays that require recognition by an antibody.The peptide sequence of the myc-tag is (in 1- and 3-letter codes, respectively): N-EQKLISEEDL-C, N-Glu-Gln-Lys-Leu-Ile-Ser-Glu-Glu-Asp-Leu-C, where N stands for Amino-terminus and C stands for Carboxy terminus. The tag is approximately 1202 Daltons in atomic mass and has 10 amino acids. It can be fused to the C-terminus and the N-terminus of a protein.
