A simple, fast, and accurate diagnosis of SARS-CoV-2 is great importance for the patient’s isolation, treatment, control COVID-19 pandemic. Although RT-qPCR accepted as gold standard, studies to improve more reliable diagnostic methods are continuing. Colorimetric reverse transcription loop-mediated isothermal amplification (RT-LAMP) a method that allows visual detection without needing expensi...

Raspberry ringspot virus (RpRSV), which has not occurred in Japan, infects many plants such as raspberry, gooseberry, cherry, grapevine, and strawberry. Biological assay, enzyme-linked immunosorbent assay (ELISA), and reverse transcription polymerase chain reaction (RT-PCR) have been introduced for the detection of RpRSV in postentry quarantine in Japan. We studied reverse transcription loop-me...

A rapid detection assay based on reverse transcription loop-mediated isothermal amplification (RT-LAMP) has been developed for detecting porcine reproductive and respiratory syndrome virus (PRRSV). The RT-LAMP assay utilized a set of six primers to amplify the open reading frame 6 (ORF6) of the PRRSV. The amplified products were analyzed by agarose gel electrophoresis or visualized by colorimet...

Nucleic acid amplification is the basis for many molecular diagnostic assays. In these cases, the amplification product must be detected and analyzed, typically requiring extended workflow time, sophisticated equipment, or both. Here we present a novel method of amplification detection that harnesses the pH change resulting from amplification reactions performed with minimal buffering capacity....

background: in human, sry (sex-determining region of the y chromosome) is the major gene for the testis-determining factor which is found in normal xy males and in the rare xx males, and it is absent in normal xx females and many xy females. there are several methods which can indicate a male genotype by the presence of the amplified product of sry gene. the aim of this study was to identify th...
