PCR products are detected most commonly using postamplification agarose gel electrophoresis and/or DNA hybridization. For reducing time in detection and confirmation, a number of investigators have reported methods to simplify or even eliminate the need to perform postamplification assays. For example, molybodate (2) or some intercalating agents (3) have been used to measure the degree of DNA a...

The data in this article are related to the research article entitled "Optimization of melting analysis with TaqMan probes for detection of KRAS, NRAS, and BRAF mutations" Botezatu et al. [1]. Somatic mutations in the PIK3CA gene ("hot spots" in exons 9 and 20) are found in many human cancers, and their presence can determine prognosis and a treatment strategy. An effective method of mutation s...

Aptamers are ssDNA or RNA that binds to wide variety of target molecules with high affinity and specificity produced by systematic evolution of ligands by exponential enrichment (SELEX). Compared to RNA aptamer, DNA aptamer is much more stable, favourable to be used in many applications. The most critical step in DNA SELEX experiment is the conversion of dsDNA to ssDNA. The purpose of this stud...

Single-stranded conformational polymorphism (SSCP) analysis is useful for mutation detection and polymorphism identification. To realize high-throughput SSCP analysis using a high-intensity electric field, the gel temperature must be well-controlled. We have developed an electrophoretic system having a pair of glass plates with an efficient temperature-controlling apparatus on each side of the ...

The electronic conductance at zero temperature through a quantum wire with side-connected asymmetric quantum ring (as a scatter system) is theoretically studied using the non-interacting Hamiltonian Anderson tunneling method. In this paper we concentrate on the configuration of the quantum dot rings. We show that the asymmetric structure of QD-scatter system strongly influences the amplitude an...

We present a method for rapid and accurate identification of the normal and DeltaF508 alleles of the cystic fibrosis (CF) gene in single human cells that utilizes LATE (linear after the exponential)-PCR, a newly invented form of asymmetric PCR. Detection of the single-stranded amplicon is carried out in real time, using allele-specific molecular beacons. The LATE-PCR method permits controlled a...

Background and Objectives. This study aimed to describe hematologic and molecular characterization of the interaction of hemoglobin (Hb) E and several forms of α-thalassemia causing complex thalassemia syndromes in two Cambodian families as well as to establish a rapid polymerase chain reaction (PCR) assay for simultaneous detection of Hb Constant Spring (CS) and Hb Pakse’ (PS). Design and Meth...

OBJECTIVE To develop an animal model for cytomegalovirus (CMV)-induced sensorineural hearing loss. DESIGN Guinea pig model. SETTING University of Utah otolaryngology research labs. PARTICIPANTS Thirty-one Hartley guinea pig pups were divided into 4 groups. Group 1 pups were delivered from pregnant dams inoculated with 1 x 10(5) plaque-forming units (PFU) of guinea pig CMV (gpCMV). Group 2...

BACKGROUND Genotyping of human papillomarvirus (HPV) is crucial for patient management in a clinical setting. This study accesses the combined use of broad-range real-time PCR and high-resolution melting (HRM) analysis for rapid identification of HPV genotypes. METHODS Genomic DNA sequences of 8 high-risk genotypes (HPV16/18/39/45/52/56/58/68) were subject to bioinformatic analysis to select ...

Typing of CTV based on coat protein (CP) gene has been approached in diverse ways. The basis for the assay focused on in this paper was presented some years ago and has been subject to several improvements since its appearance. Although the results obtained with this assay have been presented in diverse scientiic meetings, theses and technical seminars, so far no paper has explained the rationa...
