    Inntags: small self-structured epitopes for innocuous protein tagging.

    Nat Methods 2015 Oct 31;12(10):955-8. Epub 2015 Aug 31.

    Protein tagging is widely used in approaches ranging from affinity purification to fluorescence-based detection in live cells. However, an intrinsic limitation of tagging is that the native function of the protein may be compromised or even abolished by the presence of the tag. Here we describe and characterize a set of small, innocuous protein tags (inntags) that we anticipate will find application in a variety of biological techniques.

    Before the advent of molecular methods to tag proteins, visualization of proteins within cells required the use of antibodies directed against the protein of interest. Thus, only proteins for which antibodies were available could be visualized. Epitope tagging allows the detection of all proteins with existing sequence information, irrespective of the availability of antibodies directed against them. Read More

    Background: In vivo overexpression of proteins is a powerful approach to study their biological function, generate disease models or evaluate gene therapy approaches. In order to investigate an exogenously expressed protein, specific and sensitive detection is essential. Unfortunately, antibodies that allow histological detection of the protein of interest are not always readily available. Read More

    Incorporation of short epitope tags into proteins for recognition by commercially available monoclonal or polyclonal antibodies has greatly facilitated the detection, characterization, localization, and purification of heterologously expressed proteins for structure-function studies. A number of tags have been developed, but many epitope-antibody combinations do not work effectively for all immunochemical techniques due to the nature of the tag and the specificity of the antibodies. A highly versatile, multipurpose epitope tag is the 9 amino acid C-terminal 1D4 peptide. Read More

    The detection and purification of proteins are often time-consuming and frequently involve complicated protocols. The addition of a peptide tag to recombinant proteins can make this process more efficient. Many of the commonly used tags, such as Flagtrade mark, Myc, HA and V5 are recognized by specific monoclonal antibodies and therefore, allow immunoaffinity-based purification. Read More
