Example insert size distribution of the switchgrass BAC library. Not I digests of BAC DNA isolated from 42 random BAC clones from the switchgrass BAC library. The vector contains two Not I sites that flank the Eco RI cloning sites. The first and last lanes contain the DNA marker Lambda Ladder PFG marker (New England Biolabs, Beverly, MA) and the middle lane contains the DNA marker PFG midrange I (New England Biolabs, Beverly, MA).
