The pSG5 Vector is a eukaryotic expression vector constructed by combining pKCR2 and the Stratagene pBS vector. Because of the high copy number of this plasmid, large quantities of double-stranded DNA are obtained.

•  4.1-kb eukaryotic expression vector
•  High copy number yields large quantities of double-stranded DNA
•  Use for in vivo or in vitro expression
