Cosmid – The size of cosmid is 7900 bp and the cloning limit is 30-50 kb. It has features similar to both phase and plasmid and an example of it is super COS1; WebCosmids are plasmid vectors containing specialized sequences that facilitate their packaging into lambda phage capsids. The specialized sequences are known as cos sites. Hence the name cosmid: cos site containing plasmid. What are cos sites?

A cosmid is a type of hybrid plasmid that contains a Lambda phage cos sequence. They are often used as a cloning vector in genetic engineering. Cosmids can be used to build genomic libraries. They were first described by Collins and Hohn in 1978. Cosmids can contain 37 to 52 (normally 45) kb of DNA, … See more Cos sequences are ~200 base pairs long and essential for packaging. They contain a cosN site where DNA is nicked at each strand, 12 bp apart, by terminase. This causes linearization of the circular cosmid with two "cohesive" … See more Cosmids are predominantly plasmids with a bacterial oriV, an antibiotic selection marker and a cloning site, but they carry one, or more recently two, cos sites derived from … See more Commonly used vectors include "SuperCos 1" See more • Stryer, Lubert (1995) Biochemistry 4th ed.
