Patent number: 6143531Abstract: The present invention provides an improved method for the synthesis of double stranded DNA, particularly complementary DNA for the construction of directional complementary DNA libraries. The method comprises synthesizing a first strand of DNA complementary to a selected RNA or DNA template by contacting with the template a linker/primer comprising a selected restriction site, a suitable RNA or DNA dependent DNA polymerase, and substrates comprising a deoxyribonucleotide triphosphate analog. The linker/primer and deoxyribonucleotide triphosphate analog are selected such that incorporation of the nucleotide analog in the first strand substantially protects the double stranded DNA from cleavage, under conditions sufficient to cleave or substantially cleave the linker/primer, at the selected restriction site.Type: GrantFiled: July 22, 1997Date of Patent: November 7, 2000Assignee: StratageneInventors: William David Huse, Connie Jo Hansen
