BACKGROUND High resolution melting (HRM) is a simple, flexible and low-cost mutation screening technique. The methylenetetrahydrofolate reductase (MTHFR) gene encoding a critical enzyme, potentially affects susceptibility to some congenital defects like congenital heart disease (CHD). We evaluate the performance of HRM for genotyping of the MTHFR gene C677T locus in CHD cases and healthy contro...

Background: The High Resolution Melting (HRM) method is a new scanning method for detecting unknown changes in DNA and its advantages have persuaded researchers to recruit it as a screening method. Objectives: Here, we developed a HRM method to screen R188H SNP (rs3218536) of XRCC2 and compared the results with a well known PCR-RFLP technique. Materials and Methods: Genomic ...

BACKGROUND DNA methylation is a highly characterized epigenetic modification of the human genome that is implicated in cancer. The altered DNA methylation patterns found in cancer cells include not only global hypomethylation but also discrete hypermethylation of specific genes. In particular, numerous tumor suppressor genes undergo epigenetic silencing because of hypermethylated promoter regio...

PCR revolutionized genetic analysis by enabling selective amplification of targeted sequences that, as a consequence of massive enrichment, could undergo genetic analysis by a variety of methodologies. The subsequent addition of a double-stranded DNA intercalating dye to the master mix was a key adaptation to PCR that allowed monitoring of amplification in real time, thus enabling quantificatio...

lentiviral vectors (lvs) are useful vehicle for genetransfer to dividing and non-dividing cells and genetic manipulations. however, the use of lentiviruses in studies requires an accurate titration technique.quantitative real-time pcr (qpcr) is a sensitive technique for the indication and quantitation of retrovirals particles. in this study, we used the qpcr for lentiviral vector titeration. th...

In this article, we show that high resolution melting analysis (HRM) is a sensitive and specific method for the detection of methylation. Methylated DNA and unmethylated DNA acquire different sequences after bisulphite treatment resulting in PCR products with markedly different melting profiles. We used PCR to amplify both methylated and unmethylated sequences and assessed HRM for the determina...

Virulent strains of Shiga toxin-producing Escherichia coli (STEC) serogroups O103 and O121 are considered adulterants in beef. Two high-resolution melting (HRM) real-time PCR assays were standardized for the specific detection discrimination potentially virulent avirulent E. O121. The HRM assay offered possibility to distinguish clearly STEC O103:H2 from O103:H25. two extensively validated usin...
