Temperature affects both the stability of nucleic acid detectors and efficiency DNA amplification. In this study, temperature flow inside a detector were simulated results used to design vents for instrument casing. A test platform was constructed collect experimental data that simulation validation. The showed error less than ±3 K. total two heat-dissipation schemes designed based on new casin...

INTRODUCTION The aim of the study was to evaluate the clinical usefulness of a one-step nucleic acid amplification assay (OSNA) for intraoperative detection of metastases to sentinel lymph nodes (SLNs) in comparison to examination of frozen sections, and to summarize the results of previous studies. MATERIAL AND METHODS We enrolled 98 patients aged 58.13 ±10.74 years treated surgically for br...

BACKGROUND The real-time monitoring of polynucleotide amplification is at the core of most molecular assays. This conventionally relies on fluorescent detection of the amplicon produced, requiring complex and costly hardware, often restricting it to specialised laboratories. PRINCIPAL FINDINGS Here we report the first real-time, closed-tube luminescent reporter system for nucleic acid amplifi...

Diagnostic tools for biomolecular detection need to fulfill specific requirements in terms of sensitivity, selectivity and high-throughput in order to widen their applicability and to minimize the cost of the assay. The nucleic acid amplification is a key step in DNA detection assays. It contributes to improving the assay sensitivity by enabling the detection of a limited number of target molec...

INTRODUCTION Genital Chlamydia trachomatis infection is the leading cause of bacterial sexually transmitted diseases in industrial countries, particularly among young people. The consequences of chlamydial infections may involve pelvic inflammatory disease, ectopic pregnancy and tubal factor infertility. METHODS Available tests for detection of chlamydia in men and women include culture in ti...

The selection of nucleic acid aptamers is an increasingly important approach to generate specific ligands binding to virtually any molecule of choice. However, selection-inherent amplification procedures are prone to artificial by-product formation that prohibits the enrichment of target-recognizing aptamers. Little is known about the formation of such by-products when employing nucleic acid li...
