چکیده

Denaturing gradient gel electrophoresis (DGGE) is widely used in microbial ecology. We tested the effect of fluorophore-labeled primers on DGGE band migration, sensitivity, and normalization. The fluorophores Cy5 and Cy3 did not visibly alter DGGE fingerprints; however, 6-carboxyfluorescein retarded band migration. Fluorophore modification improved the sensitivity of DGGE fingerprint detection and facilitated normalization of samples from multiple gels by the application of intralane standards.

Diversity of eukaryotic plankton of aquaculture ponds with Carassius auratus gibelio, using denaturing gradient gel electrophoresis

PCR-denaturing gradient gel electrophoresis (DGGE) and canonical correspondence analysis (CCA) were used to explore the relationship between eukaryotic plankton community succession and environmental factors in two aquaculture pond models with gibel carp Carassius auratus gibelio. The main culture species of pond 1 were gibel carp and grass carp, and the combined density was 46224 fingerling/ha...

Microbial community fingerprinting by differential display-denaturing gradient gel electrophoresis.

Complex microbial communities exhibit a large diversity, hampering differentiation by DNA fingerprinting. Herein, differential display-denaturing gradient gel electrophoresis is proposed. By adding a nucleotide to the 3' ends of PCR primers, 16 primer pairs and fingerprints were generated per community. Complexity reduction in each partial fingerprint facilitates sample comparison.

The Comparison of the Effectiveness of a Modified Conformation Sensitive Gel Electrophoresis with Denaturing High Performance Liquid Chromatography

Background: Several methods have been developed for detection of sequence variation in genes and each has its advantages and disadvantages. A disadvantage of them is that the simpler, cost-effective methods are commonly perceived as being less sensitive in their detection of sequence variation, whereas those with proven sensitivity have a requirement for complex or expensive laboratory equipmen...

Design and Evaluation of PCR Primers for Denaturing Gradient Gel Electrophoresis Analysis of Plant Parasitic and Fungivorous Nematode Communities

A PCR-DGGE primer pair, Tyl2F-Tyl4R, specific to plant parasitic and fungivorous nematodes was designed based on the 18S rRNA gene. The results of community analysis using the primers showed that they are specific to the order Tylenchida. This primer pair detected species belonging to Tylenchida with high sensitivity and high resolution. The number of detected species of plant parasitic and fun...

Combination of multiplex PCR and PCR-denaturing gradient gel electrophoresis for monitoring common sourdough-associated Lactobacillus species.

A combination of denaturing gradient gel electrophoresis (DGGE) and a previously described multiplex PCR approach was employed to detect sourdough lactobacilli. Primers specific for certain groups of Lactobacillus spp. were used to amplify fragments, which were analyzed by DGGE. DGGE profiles obtained from Lactobacillus type strains acted as standards to analyze lactobacilli from four regional ...
