| 20120129225 | METHODS AND REAGENTS FOR MOLECULAR CLONING - The present invention provides compositions, methods, and kits for covalently linking nucleic acid molecules. The methods include a strand invasion step, and the compositions and kits are useful for performing such methods. For example, a method of covalently linking double stranded (ds) nucleic acid molecules can include contacting a first ds nucleic acid molecule, which has a topoisomerase linked to a 3′ terminus of one end and has a single stranded 5′ overhang at the same end, with a second ds nucleic acid molecule having a blunt end, such that the 5′ overhang can hybridize to a complementary sequence of the blunt end of the second nucleic acid molecule, and the topoisomerase can covalently link the ds nucleic acid molecules. The methods are simpler and more efficient than previous methods for covalently linking nucleic acid sequences. | 05-24-2012 |

| 20130023012 | Recombinase-Based Methods for Producing Expression Vectors and Compositions for Use in Practicing the Same - Methods are provided for producing a vector that includes at least one spliceable intron. In the subject methods, intron containing vectors are produced from donor and acceptor vectors that each include a site specific recombinase site, where the subject donor and acceptor vectors further include splice donor and acceptor sites that, upon site specific recombination of the donor and acceptor vectors, define an intron in the product vector of the recombination step. Also provided are compositions for use in practicing the subject methods, including the donor and acceptor vectors themselves, as well as systems and kits that include the same. The subject invention finds use in a variety of different applications, including the production of expression vectors that encode C-terminal tagged fusion proteins, the production of expression vectors that encode pure protein and not a fusion thereof, and the like. | 01-24-2013 |
