  • PEPTIDE LINKERS FOR EFFECTIVE MULTIVALENT PEPTIDE BINDING
    Publication number: 20100158823
    Abstract: Short single chain peptides having affinity for a target surface often lack the binding durability required for certain commercial applications. One way to improve durability is to promote multivalent binding by linking together binding sequences using peptide linkers. However, the resulting single chain binding peptides often suffer from linker entropy. It has been discovered that the use of rigid peptide linkers when linking together multiple binding sequences enhances the binding affinity of the resulting single chain peptide.

  • SITE-SPECIFIC INTEGRATION AND STACKING OF TRANSGENES IN SOYBEAN VIA DNA RECOMBINASE MEDIATED CASSETTE EXCHANGE
    Publication number: 20100162436
    Abstract: A targeting method is described that allows precise cassette replacement at a previously characterized genetic locus. A target DNA construct containing a pair of incompatible FRT sites flanking a target cassette was introduced into soybean by regular biolistic transformation. Transgenic events containing a single complete copy of the target site were then selected and retransformed with a donor DNA construct containing the identical pair of incompatible FRT sites flanking a donor cassette. Precise DNA cassette exchange happened between the target cassette and the donor cassette via recombinase mediated cassette exchange (RMCE) so that the donor cassette was introduced at the exact genomic site previously occupied by the target cassette. Through repeated RMCE using additional incompatible FRT sites, multiple groups of transgenes can be stacked at the same genomic locus.

The selective deposition of the display elements can be achieved by ink jet printing methods, screen printing methods or other printing methods. In some embodiments the electrodes are printed onto the substrate before selective deposition of the display elements, while in other embodiments the substrate is provided having the electrodes already disposed on it. In still other embodiments, the sequence of printing of electrodes and electrophoretic display elements can be varied.
