Leaders in Random Shear BAC Library Construction

Custom Competent Cells Your project can benefit from our expertise in library construction, screening, cloning and other genomic analysis. Lucigen scientists have constructed over 1,000 libraries including more than 100 Random Shear BAC Libraries from metagenomes, microbes, and plant and animal species for clients all over the world.

Lucigen can also screen your library or provide the tools for you to efficiently screen libraries on your own. Complete package service, such as BAC library construction, library screening, genome-wide BAC end sequencing, building the BAC minimum tile of a genome or chromosome, position-cloning of candidate genes/QTLs/transgenic loci, or complete NextGen Roche 454 or Sanger sequencing and analysis are available. We can also create custom clones from otherwise uncloneable DNA.
