Images of long PCR products

DNA strands made using William Stemmer's parallel overlap assembly PCR method. Short oligos whose sequences 'cover' a desired long sequence are mixed and PCRed together. In this case cyclic boundary conditions for the overlaps mean that DNA of arbitrary length may be formed. Stretched out we believe that some of these molecules should be at least 3 microns long. The 50 nm stars or blobs seen in the background of these images are DNA dendrimers.
