Construction of a gorilla fosmid library and its PCR screening system.

摘要

A gorilla fosmid library of 261,120 independent clones was constructed and characterized. The fosmid vector is similar to the cosmid in average insert size of ca. 40 kb but contains the F factor for replication, and it is more resistant to recombination. This clone library represents about 3.7 times coverage of the gorilla genome. A simple screening system by PCR was established, and we successfully found 9 clones that cover the entire Hox A gene cluster of the gorilla genome. This gorilla fosmid DNA library is a useful resource for comparative genomics of human and apes.
