Universal PCR primers for ribosomal protein gene introns of fish

PCR Primers for Metazoan Mitochondrial 12S Ribosomal DNA Sequences

BACKGROUND Assessment of the biodiversity of communities of small organisms is most readily done using PCR-based analysis of environmental samples consisting of mixtures of individuals. Known as metagenetics, this approach has transformed understanding of microbial communities and is beginning to be applied to metazoans as well. Unlike microbial studies, where analysis of the 16S ribosomal DNA ...

Importance of introns for expression of mouse ribosomal protein gene rpL32.

The importance of intronic sequences for expression of the mouse ribosomal protein gene rpL32 was evaluated by transfection experiments with a series of mutant constructs in which one or more of the three rpL32 introns was totally or partially deleted. When transiently transfected into monkey kidney (COS) cells or stably transfected into mouse L cells, a mutant that lacked all three introns was...

High-throughput expression-PCR using universal plasmid-specific primers.

DETECTION OF BACTERIA BY AMPLIFYING THE 16S rRNA GENE WITH UNIVERSAL PRIMERS AND RFLP

Background: There is a conserved portion in the 16S rRNA gene of bacteria which can be amplified by the universal PCR method. This fragment is 996 bp in length. In this method, only one set of universal primers is used for the amplification of the conserved region of the 16S rRNA gene, in common bacterial pathogens. Therefore, using the universal PCR method, these bacteria are detectable on...

Universal primers to amplify the complete mitochondrial 12S rRNA gene in marine fish species.

A pair of new universal 12S mitochondrial rRNA gene primers was designed through multiple alignment analysis of the mitochondrial tRNA(Phe) and the 5' region of 16S mitochondrial rRNA genes of different kinds of fishes. The primers were successfully used to amplify an expected product fragment of about 1.2 kb from various marine fish species, and the amplified DNA fragment was recognized to con...
