  • Publication number: 20130316350
    Abstract: The present invention relates to the fields of biotechnology and molecular biology. In particular, the present invention relates to the construction and use of nucleic acid molecules comprising cloning sites which differ in nucleotide sequence. In particular embodiments, the present invention relates to nucleic acid molecules which contain recombination sites with different primer binding sites. These different primer binding sites may be used to sequence different ends of nucleic acid segments located between the two recombination sites.

  • Publication number: 20130004996
    Abstract: The present invention provides compositions and methods for recombinational cloning. The compositions include vectors having multiple recombination sites and/or multiple topoisomerase recognition sites. The methods permit the simultaneous cloning of two or more different nucleic acid molecules. In some embodiments the molecules are fused together while in other embodiments the molecules are inserted into distinct sites in a vector. The invention also generally provides for linking or joining through recombination a number of molecules and/or compounds (e.g., chemical compounds, drugs, proteins or peptides, lipids, nucleic acids, carbohydrates, etc.) which may be the same or different.

  • Patent number: 8338091
    Abstract: The present invention is in the fields of biotechnology and molecular biology. More particularly, the present invention relates to cloning or subcloning one or more nucleic acid molecules comprising one or more type IIs restriction enzyme recognition sites. The present invention also embodies cloning such nucleic acid molecules using recombinational cloning methods such as those employing recombination sites and recombination proteins. The present invention also relates to nucleic acid molecules (including RNA and iRNA), as well as proteins, expressed from host cells produced using the methods of the present invention.

  • Publication number: 20100009342
    Abstract: Provided is a method for controlling the degree of labeling (DOL) of a carrier molecule or solid support by the addition of a reactive label competitor to the labeling reaction. When the reactive label competitor is added to the labeling solution the competitor competes with the carrier molecule or solid support for the label, reducing the number of labels available to conjugates to the carrier molecule or solid support. This provides for a facile method that predictably alters the DOL of a carrier molecule or solid support.
