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).
DNASU and Addgene are central repositories for plasmid clones and collections that may also be helpful.
pUC19 is isolated from E. coli ER2272 (dam+ dcm+ EcoK M-) by a standard plasmid purification procedure.
