Title: Efficient directional genetic cloning system
Inventor: MIKI TORU
IPC: C12N15/16
Filed: 1990-07-30
Granted: 1996-05-21
Abstract: A highly efficient genetic cloning system is disclosed which is particularly useful for cloning cDNA copies of eukaryotic mRNAS and can direct the orientation of inserts in plasmid composite vectors with large cloning capacities. Cleavage of such vector DNA, by the restriction enzyme Sfil, for example, creates two different non-symmetrical 3' extensions at the ends of vector DNA. Using a linker-primer and an adaptor, cDNA is prepared to have two different sticky ends which can be ligated to those of the vector. When the cDNA fragments and the vector DNAs are mixed, both the molecules can assemble without self-circulariza-tion due to base-pairing specificity. This system provides (1) high cloning efficiency (107-108 clones/g poly (A)+ RNA), (2) low background (more than 90 % of the clones contain inserts), (3) directional insertion of cDNA fragments into the vectors, (4) presence of a single insert in each clone, (5) accommodation of long inserts (up to 10 kb), (6) a mechanism for rescue of the plasmid part from a .lambda. genome, and (7) a straightforward protocol for library preparation.
