What is the pUC19 plasmid?

What is the pUC19 plasmid?

pUC19 is a commonly used cloning vector that conveys the Amp resistance. The molecule is a small double-stranded circle, 2686 base pairs in length, and has a high copy number. NEB offers a selection of common cloning plasmids and DNAs for use as substrates.

Is pUC19 ampicillin resistance?

The pUC19 plasmid confers ampicillin resistance to its host through its bla gene which codes for a β-lactamase that cleaves the β-lactam ring in ampicillin. pUC19 contains a multiple cloning site within the lacZ gene and so the gene is inactivated when an insert is ligated into the site.

Which selection system is used in the pUC19 plasmid?

FabI/triclosan selection
The application of the FabI/triclosan selection marker in the pUC19-derived plasmid was first reported by Goh and Good (2008) . An improved system with a fabI gene harboring a G93V point mutation that confers enhanced resistance towards triclosan was constructed by Jang and Magnuson (2013). …

What does PBR and pUC stand for?

The Hawaii Public Utilities Commission (“PUC”) has opened a proceeding to investigate performance-based regulation for the Hawaiian Electric Companies.

Why is the plasmid pUC19 used in our transformation experiment?

Plasmid pUC19: Marker Genes This plasmid has been modified to carry a gene for resistance to ampicillin (the so-called amp-r gene), which confers ampicillin resistance to the host. It also includes a beta-galactosidase gene that, upon transformation, can complement the defective host beta-galactosidase gene.

What is pUC19 DNA?

Thermo Scientific pUC19 vector is a small, high copy number, E. coli plasmid, 2686 bp in length. It contains identical multiple cloning site (MCS) as pUC18 vector except that it is arranged in opposite orientation.

What is the primary difference between pBR322 and pUC series of vectors?

pBR322 plasmids contain the pMB1 replicon and are present at 15–20 copies per E. coli cell. pUC vectors also contain the pMB1 replicon but are present at 500–700 copies per E. coli cell.

What are pUC vectors?

pUC19 is one of a series of plasmid cloning vectors created by Joachim Messing and co-workers. The designation “pUC” is derived from the classical “p” prefix (denoting “plasmid”) and the abbreviation for the University of California, where early work on the plasmid series had been conducted.

What might explain the presence of nontransformed bacteria growing on the LB amp plate?

Explain your prediction. Bacteria which resemble the non-transformed will be found on the LB/(-) pGLO plate. These bacteria were removed from the starter plate, did not have any plasmid added to them, and were replated on an LB plate. Thus, they are virtually identical to the non-transformed starter.
