Methods and compositions for transferring DNA sequence information among vectors
First Claim
1. A method of transferring DNA sequence information from a first vector to a second vector, said method comprising:
- contacting said first vector with a set of three pairs of oligonucleotide primers under conditions sufficient to produce three different PCR products, wherein each oligonucleotide primer comprises a first region of sequence identity with said first vector and a second region which does not hybridize with said first vector and provides for homologous recombination with said second vector, whereby three different PCR products are produced; and
contacting said three different PCR products with said second vector under conditions sufficient for homologous recombination to occur;
whereby said DNA sequence information is transferred from said first vector to said second vector.

Abstract
Methods and compositions are provided for transferring DNA sequence information from a first vector to a second vector. In the subject methods, a first vector comprising a region of DNA having a sequence of interest is contacted with a set of three pairs of oligonucleotide primers under conditions sufficient to produce three different PCR products, where each product corresponds to a different reading frame. The oligonucleotide primers comprise a first region of sequence identity with the first vector and a second region permissive of site specific recombination with the second vector. The resultant PCR products are combined with the second vector under conditions sufficient for site specific recombination to occur. Also provided are kits for use in performing the subject methods.

12. A method of transferring DNA sequence information from a first plasmid into an expression plasmid, said method comprising:
-
contacting said first plasmid with a set of three pairs of oligonucleotide primers under conditions sufficient to produce three different PCR products, wherein each PCR product corresponds to a different reading frame and each oligonucleotide primer comprises a first region of sequence identity with said first plasmid and a second region which does not hybridize with said first plasmid and provides for homologous recombination with said expression plasmid, whereby three different PCR products are produced; and co-transforming said three different PCR products and said expression plasmid into a yeast host whereby homologous recombination occurs, wherein said expression plasmid comprises a DNA sequence encoding either a DNA binding domain or an activation domain of a eukaryotic transcriptional activator; whereby said DNA sequence information is transferred into said expression plasmid. - View Dependent Claims (13, 14, 15, 16, 17, 18)
