T7 tag antibodies


The T7 tag has emerged as a valuable tool in scientific research, particularly in molecular biology and protein expression studies. The T7 tag is a short peptide sequence (MASMTGGQQMG) derived from the T7 bacteriophage gene 10, which can be fused to the N or C terminus of a target protein. Its small size and minimal impact on the function of the tagged protein make it an attractive choice as a molecular tag. Researchers frequently use the T7 tag in protein expression systems, such as bacterial, insect, or mammalian cells, to facilitate the identification and purification of the recombinant protein. The T7 tag’s versatility allows for straightforward detection using specific T7 tag antibodies in various experimental assays, including Western blotting and immunoprecipitation. Moreover, the T7 tag can be employed for protein purification through affinity chromatography using T7 tag-specific resins, simplifying downstream characterization and functional studies.
