A Kan cassette (1090bp) is inserted between two bbsI sites in finger 1 of this construct. This cassette is here to provide a large drop out band when digested with BbsI. The digested backbone can then be used for building finger 1 libraries. Fingers two and three are anchor fingers which specify GCGTGG.
