First Claim
Patent Images
1. A method for in vitro cloning of a nucleic acid of interest, comprising:
- (a) mixing in vitro a first vector comprising at least a first recombination site and a second vector comprising at least a second recombination site, wherein said first and/or second vector further comprises a nucleic acid of interest;
(b) incubating said mixture in the presence of at least one recombination protein under conditions sufficient to cause recombination of at least said first and second recombination sites, thereby producing a chimeric nucleic acid molecule comprising said nucleic acid of interest;
(c) contacting one or more hosts with said mixture; and
(d) selecting for a host comprising said chimeric nucleic acid molecule, and selecting against a host comprising said first vector and against a host comprising said second vector, thereby cloning said nucleic acid of interest.

Abstract
Recombinational cloning is provided by the use of nucleic acids, vectors and methods, in vitro and in vivo, for moving or exchanging segments of DNA molecules using engineered recombination sites and recombination proteins to provide chimeric DNA molecules that have the desired characteristic(s) and/or DNA segment(s).
