The S•Tag fusion protein is one of many polypeptide tags used to facilitate the identification and purification of many targets of interest. The gene encoding the S•Tag peptide can be added into a vector with another gene that encodes a target of interest. Such vectors, which are available through the Novagen product line, are subsequently transfected into various mammalian, bacterial, or insect cell cultures. Because the target of interest and the S•Tag peptide are expressed as one protein, identification of the target is facilitated with the use of antibodies that are specific for the respective fusion tag. Optional purification of the target may be performed using chromatography techniques that allow for the binding and removal of the respective fusion tag, if desired.
