  • pUC19 Vector


    pUC19 is a commonly used plasmid cloning vector in E.coli. The molecule is a small double-stranded circle, 2686 base pairs in length, and has a high copy number. pUC19 carries a 54 base-pair multiple cloning site polylinker that contains unique sites for 13 different hexanucleotide-specific restriction endonucleases (1).
