Method For Constructing And Modifying Large Dna Molecules

总结

This Invention Provides A Method For Combining Overlapping Dna Molecules Comprising: (A) Providing First And Second Dna Fragments, The First Having A Region Homologous To A Region In The Second; (B) Tagging The First Dna Fragment With A Selectable Marker; (C) Cloning The First Dna Sequence Into A Retrieval Vector To Form A Dna-Vector Complex; (D) Linearizing The Dna-Vector Complex; And (E) Inserting The First Dna Fragment From The Dna-Vector Complex Into The Second Dna Fragment Using Homologous Recombination To Form A Combined Dna Molecule; And (F) Removing The Selectable Marker, Thereby Generating A Combined Dna Molecule. The Invention Further Provides A Vector For Retrieving And Inserting A Selected Dna Molecule Into A Target Dna Molecule.

Title: Method for constructing and modifying large DNA molecules
Usefulness: Method for constructing and modifying large DNA molecules
Summary: The method is useful for bacterial artificial chromosome manipulation to aid in future studies of gene function in the post-genomic era. The method is useful for engineering any large DNA fragments or inserting large DNA fragments into the Escherichia coli chromosome. It is also useful for constructing and modifying much larger DNA molecules such as human artificial chromosomes.
Novelty: Combining overlapping DNA molecules, useful for human artificial chromosome manipulation for gene function study, by inserting a first DNA fragment from a DNA-vector complex into a second DNA fragment by homologous recombination
