results the results showed that nl1-gc/ls2 primer set could yield species-specific amplicons, which were well distinguished and allowed better species discrimination than that generated by the its3-gc/its4 primer set, in both dgge and ttge profiles. all five candida species were discriminated by dgge and ttge using the nl1-gc/ls2 primer set. conclusions comparison of dgge and ttge profiles obta...

conclusions with regard to improving the understanding of the differences in the biodiversity of the fecal microbiota between rd infants and h infants, the findings of this study can provide a possible basis to reveal the relationship between rd and intestinal microbiota. objectives this study aimed to reveal the changes in the biodiversity of the fecal microbiota of infants with rd. patients a...

We used denaturing gradient gel electrophoresis to detect the beta-thalassemia mutations in the Chinese population. By amplifying the beta-globin gene in four separate fragments and electrophoresing the amplified DNA in two gels, we were able to distinguish all the 12 known mutations on the basis of the mobility of the homoduplexes and heteroduplexes. We conclude that denaturing gradient gel el...

The intestinal bacteria community structure and diversity of the Oriental armyworm, Mythimna separata (Walker) (Lepidoptera: Noctuidae), was studied by analysis of a 16S rDNA clone library, denaturing gradient gel electrophoresis,and culture-dependent techniques. The 16S rDNA clone library revealed a bacterial community diversity comprising Cyanobacteria, Firmicutes, Actinobacteria, Gracilicute...

Single base pair differences between otherwise identical DNA molecules can result in altered melting behavior detectable by denaturing gradient gel electrophoresis. We have developed a simplified procedure for using denaturing gradient gel electrophoresis to detect base pair changes in genomic DNA. Genomic DNA is digested with restriction enzymes and hybridized in solution to labeled single-str...
