Simplified hepatitis C virus genotyping by heteroduplex mobility analysis.
Heteroduplex mobility analysis (HMA) was used to genotype hepatitis C viruses (HCV) with PCR fragments derived from the 5' untranslated region (5'-UTR) or the NS5b region. HCV 5'-UTR fragments were amplified from 296 serum samples by use of a combined reverse transcription-PCR assay, and the genotypes of isolates were determined by sequencing. HCV genotype distributions in Australia were 39% fo...
متن کاملAnalysis of quasispecies variation in single and mixed viral infection
Population diversity was examined in individual and natural mixed infections of Cowpea chlorotic mottle virus (CCMV) and Cucumber mosaic virus (CMV) isolates in two systemic hosts, cowpea and Nicotiana benthamiana. Isolates of CCMV and CMV obtained from a cowpea field in Arkansas were separated biologically in cowpea and tobacco plants, respectively. After separation, individual and mixed cultu...
متن کاملGenotyping of enteric adenoviruses by using single-stranded conformation polymorphism analysis and heteroduplex mobility assay.
Single-stranded conformation polymorphism (SSCP) analysis and heteroduplex mobility assays (HMAs) were used to identify and genotype enteric adenoviruses (EAd). The results were compared to those of restriction endonuclease assays, species-specific PCRs, and direct nucleotide sequence analyses. Of the 31 stool samples tested, 15 isolates were identified as EAd and 7 were identified as nonenteri...
متن کاملGenotyping hepatitis C virus by heteroduplex mobility analysis using temperature gradient capillary electrophoresis.
The genotype of the infecting hepatitis C virus (HCV) helps determine the patient's prognosis and the duration of treatment. Heteroduplex mobility analysis (HMA) is a rapid, inexpensive method for genotyping of HCV that does not require sequencing. We developed an HMA that uses temperature gradient capillary electrophoresis (TGCE) to differentiate HCV genotypes. A 56-bp region of the HCV 5' unt...
متن کاملHeteroduplex cleavage analysis using S1 nuclease.
A variety of methods have been developed to screen for genetic mutations. Most rely on the comparative analysis of polymerase chain reaction (PCR) products. Single-strand conformational polymorphism (4), the most widely used technique, relies on sequence-dependent conformational electrophoretic mobility differences between wild-type (WT) and mutant strands; whereas, heteroduplex analysis (5,8),...
