Cosmid Definitions:

  1. A plasmid vector with lambda phage cos sites that can be packaged in a phage capsid; it is useful for cloning large DNA fragments.

    Prescott's Microbiology 9th Edition by Joanne Willey, Linda Sherwood, Christopher J. Woolverton



  2. A hybrid cloning vector capable of accommodating inserts of up to 50kb.

    Essential Microbiology by Stuart Hogg



Cosmid Notes:

Cosmids are hybrid plasmids that contain a cos sequence of Lambda phage. The DNA sequences of cosmids (plasmid + cos sites = cosmids) are originally from lambda phage. They are usually in genetic engineering serving the purpose of cloning vector. Genomic libraries can be built by utilizing cosmids.
