Definitions

from The American Heritage® Dictionary of the English Language, 4th Edition

  • n. Genetics A hybrid vector that has been spliced with plasmid DNA for cloning large genes or gene fragments.

from Wiktionary, Creative Commons Attribution/Share-Alike License

  • n. A type of plasmid (often used as a cloning vector) constructed by the insertion of cos sequences, which are DNA sequences of the lambda phage.

  • n. (genetics) a large vector that is made from a bacteriophage and used to clone genes or gene fragments

Etymologies

Blend of cos (sequence), sequence of DNA allowing the cosmid to form as a circle (short for cohesive ends) and plasmid.
(American Heritage® Dictionary of the English Language, Fourth Edition)
Blend of cos and plasmid (Wiktionary)

Examples

  • E. coli and 25 µg/ml for M. smegmatis; and hygromycin B, 100 µg/ml for oppA (Rv1280c) of M. tuberculosis was amplified from cosmid MTCY50 using the primer pair

  • The alphaT2ib open reading frame was integrated into an adenoviral cosmid vector for production of recombinant adenovirus (AdV) - alphaT2ib.

  • However, the linearized cosmid produced an incomplete assembly because the two DNA termini, though greatly over-represented in the clone library used for sequencing, were separated from neighboring sequences by gaps of ~1. 4 and 1.8 kb.

  • These gap sizes were reduced, but not eliminated, by shearing the linear cosmid into smaller fragments.

  • 1987 (Burke et al. 1987) permitted much larger segments of DNA to be ordered and stored for sequencing than was possible with plasmid or cosmid libraries.
