Location of important features in the pUC19 cloning vector plasmid. A p R is the ampicillin resistance gene, lacZα is the lacZ gene, and ori is the origin of replication. The numbers represent base pairs measured from an arbitrary reference point on the vector, labeled 0. The basepair numbers increase clockwise until the reference point is reached again after 2686 bp.. Strain DH5α/pUC19. DH5 is a non-mutagenized derivative of DH1, which transforms more efficiently due to a deoR mutation pUC18 and pUC19 vectors. The pUC18 and pUC19 plasmids enable successful cloning of large DNA fragments (larger than those cloned with a M13 mp18 RF Phage Vector). These cloning vectors contain a multiple cloning site at the lacZ' region that enables recombinant plamids to be verified via blue/white colony screening using agar plates containing IPTG.

DH5α/pUC19 was included as a control to determine staining levels of live and heat-treated dead cells. Samples were excited with a 488 nm air-cooled argon ion laser in the CyFlow SL flow cytometer (Partec GmbH). Threshold settings were enabled on forward scatter to exclude cell debris. The forward and side scatter dot plot was used to identify and gate cell populations. Fluorescence was measured at 520 nm. Viable and dead cell populations were counted using the Partec, FloMax.

Explore literature, identify clinical trials, and compounds used in them The plasmid must contain the lacZα, and examples of such plasmids are pUC19 and pBluescript. The E. coli cell should contain the mutant lacZ gene with deleted sequence (i.e. lacZΔM15), and some of the commonly used cells with such genotype are JM109, DH5α, and XL1-Blue. It should also be understood that the lac operon is affected by the presence of glucose. The protei 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.It is a circular double stranded DNA and has 2686 base pairs.. Transformation of non-competent Escherichia coli JM109 was accomplished using pUC19 as donor plasmid and sepiolite as the acicular material to promote cell piercing via application of friction with a polystyrene stick or a magnetic bar on the surface of a hydrogel containing agar. An automatic spreading setup was built with a conventional stirring plate and compared to manual spreading. Several parameters were optimized, namely, the agar content of the hydrogel (2%), concentration.

The development of gel electrophoresis as a method of separating and analyzing DNA has been one of the forces driving the revolution in molecular biology for the last 20 years. In principle, DNA gel electrophoresis is conceptually easy to understand and technically easy to execute. In practice, there are a lot of small details that affect.
We performed a screen for extrachromosomal circular DNAs containing segments of genomic yeast DNA. We found 1,756 such extrachromosomal circular DNAs containing about 23% of the total yeast genomic information.

pUC19 is a small, high-copy number E. coli plasmid cloning vector containing portions of pBR322 and M13mp19 (1). It con-tains the pMB1 origin of replication from pBR322, but it lacks the rop gene and carries a point mutation in the RNAII transcript (G 2975 in pBR322 to A 1308 in pUC19; 2).

pUC19 is a plasmid cloning vector created by Messing and co-workers in the University of California. p in the name stands for plasmid and UC represents the University in which it was created.It is a circular double stranded DNA and has 2686 base pairs . pUC19 is one of the most widely used vector molecules as the recombinants, or the cells into which foreign DNA has been introduced, can be. In addition, pUC19 plasmid was extracted from the transformed strain, and the AS-1 wild-type strain became resistant to ampicillin by reintroduction of this plasmid. Thus, the AS-1 strain was able to express the ampicillin resistance gene encoded by the pUC19 plasmid. Which led us to conclude that strain AS-1 could be used as a eurytrophic recombinant host Verify the sequence of each colony by sequencing from the pUC19 backbone using the pUC19-Fwd or pUC19-Rev primer.

There are two primary methods for transforming bacterial cells: heat shock and electroporation. In both cases, the bacterial cells have to be made competent or permeable to plasmids that you would like the cell to propagate . CRISPR/Cas13a (known previously as C2c2) is a class 2 type VI-A ribonuclease capable of targeting and cleaving single-stranded RNA (ssRNA) molecules of the phage genome. Here, we employ CRISPR/Cas13a to engineer interference with an RNA virus, Turnip Mosaic Virus (TuMV), in plants Salmonella enterica subsp. enterica serotype Enteritidis BM4361 and BM4362 were isolated from the same patient. BM4361 was susceptible to aminoglycosides, whereas BM4362 was resistant to tobramycin owing to synthesis of a 6′- N -acetyltransferase type I [AAC(6′)-I].

All candidate reads were aligned against the new reference. To enable better delineation of the allele structure, each read was fragmented into 1 kb. The resulting full-length products were amplified by PCR and cloned into the pUC19 vector.
