  • Avidity ATUM AviTag™ vectors and other plasmids
    Avidity is providing vectors for cloning and expression of C-terminal or N-terminal AviTagged proteins that are either IPTG inducible (T5 promoter) or Rhamnose inducible (Rha promoter).  The vectors also are available with a choice of short flexible linker or stiff, extended linker between the target protein and the AviTag™.  
    Avidity also offers a pBirAcm plasmid that can be transformed into an E.coli strain creating a BirA overproducing cell line.
