  • Vector backbone
    pUC21 (Addgene plasmid #49787)
  • Backbone manufacturer
    Messing Lab
  • Backbone size (bp) 3090
  • Modifications to backbone
    The bla gene of pUC21 was replaced with the Kanamycin resistance gene from Tn903 by cutting pUC21 with BspHI, filling in the ends, and inserting the Tn903 fragment. The HindIII and SmaI sites have been removed from the Kanamycin Resistance gene so that these sites within the MCS are now unique and can be used for cloning.
