The construction of cosmid libraries which can be used to transform eukaryotic cells

F G Grosveld et al. Nucleic Acids Res. .

Abstract

Cosmid vectors have been developed which carry selective markers for growth in bacteria (beta lactamase gene) and animal cells (the Herpes Simplex virus thymidine kinase gene, the transposon Tn-5 aminoglycosyl 3' phosphotransferase gene and the E. coli guanine phosphoribosyltransferase gene). The design of the cosmids allows the exchange of the eukaryotic markers in recombinant cosmids. Human and mouse cosmid libraries containing DNA inserts of about 40kb have been generated by an improved method. Several clones from the human beta-globin locus were isolated. These cosmids transform mouse L cells at high efficiency in both circular and linear form. The newly introduced genes are expressed accurately in L cells.
