Bacterial Artificial Chromosome (BAC) acts as a vector to artificially carry DNA into the cell of a bacterium, such as Escherichia coli, to make a BAC clone. In general, BAC clones can carry inserts of DNA up to 200,000 base pairs long. Recently, BAC is used to create BAC libraries which are preferable for genome sequencing, physical maps constructing, and gene cloning. As a leading supplier in BAC library construction services, Creative Biogene is committed to providing you the most affordable BAC library construction services with fastest turnaround time to satisfy your downstream needs.
