25 A single-tube method – ligation mediated real-time PCR high-resolution melt analysis 26 (LMqPCR HRMA) – was modified for rapid typing of ESKAPE-pathogens. A 97 % 27 agreement (60/62 isolates) was achieved in comparison to PFGE which indicates that 28 LMqPCR HRMA is a rapid and accurate screening tool to monitor for nosocomial outbreaks. 29 on O cber 1, 2017 by gest ht://jcm .sm .rg/ D ow nla...

A rapid competitive PCR method was developed to quantify DNA on the LightCycler. It rests on the quantitative information contained in the melting curves obtained after amplification in the presence of SYBR Green I. Specific hybridization probes are not required. Heterologous internal standards sharing the same primer binding sites and having different melting temperatures to the natural PCR pr...

BACKGROUND Single-base pair missense mutations in exons 10, 11, 13, 14, 15, and 16 of the RET protooncogene are associated with the autosomal dominant multiple endocrine neoplasia type 2 (MEN2) syndromes: MEN2A, MEN2B, and familial medullary thyroid carcinoma. The current widely used approach for RET mutation detection is sequencing of the exons. METHODS Because RET mutations are rare and the...

Melting fine structure of the nuclear DNA isolated from the filamentous fungus Fusarium graminearum Schwabe is presented. Optical melting profiles of nuclear DNA were analyzed by using a combination of curve fitting and derivative techniques. The "melting components" were obtained from the derivative curve by a simple decomposition technique. Differential optical melting curves of unsheared nuc...

Two reports in this issue of Clinical Chemistry describe novel mutations in thrombophilia genes (1, 2). The authors of the reports describe variants detected by the identification of a melting temperature (Tm) different from the expected Tm of the target mutation and from the Tm of the wild-type sequence. The variants reported in this issue are A20218G in the prothrombin (factor II) gene and C1...

A phase diagram of water in single-walled carbon nanotubes at atmospheric pressure is proposed, which summarizes ice structures and their melting points as a function of the tube diameter up to 1.7 nm. The investigation is based on extensive molecular dynamics simulations over numerous thermodynamic states on the temperature-diameter plane. Spontaneous freezing of water in the simulations and t...

High-throughput methods for assaying DNA variation require two important steps: (i) discriminating the variation and (ii) detecting the signal. In this report, we describe a novel SNP genotyping method that we refer to as melting curve analysis of SNPs (McSNP). McSNP combines a classic approach for discriminating alleles, restriction enzyme digestion, with a more recent method for detecting DNA...

influenza a virus is now considered to be widespread in poultry and has demonstrated the ability to infect humans in iran. for laboratory diagnosis of these respiratory viruses, it is essential to have rapid methods, able to detect viruses in early stages of the infection in clinical specimens. the real-time reverse-transcription polymerase chain reaction n (rrt-pcr) assay has been established ...

BACKGROUND Heteroduplex scanning techniques usually detect all heterozygotes, including common variants not of clinical interest. METHODS We conducted high-resolution melting analysis on the 24 exons of the ACVRL1 and ENG genes implicated in hereditary hemorrhagic telangiectasia (HHT). DNA in samples from 13 controls and 19 patients was PCR amplified in the presence of LCGreen I, and all 768 ...
