摘要: Large-insert genomic libraries are necessary for physical mapping of large chromosomal regions, isolation complete genes, and use as intermediates in DNA sequencing entire genomes. Construction BAC PAC is detailed the unit, including preparation or vector cloning by digestion with BamHI EcoRI, dephosphorylation alkaline phosphatase, purification through pulsed-field gel electrophoresis (PFGE). For high-molecular weight cloning, procedures embedding total from lymphocytes animal tissue cells also provided. Other protocols detail partial MboI a combination EcoRI endonuclease methylase (including methods optimizing extent digestion), subsequent size fractionation preparative PFGE. Finally, plasmid analyzing clones presented.
