We have developed a highly accurate, low-cost, single-step, mutagenically separated polymerase chain reaction (MS-PCR) method for the determination of angiotensin II type-1 receptor (AT(1)) A1166C gene polymorphism. The genotypes are determined using the microtiter array diagonal gel electrophoresis (MADGE) system. We have compared the MS-PCR method with allele-specific oligonucleotide hybridiz...

This report describes three case studies of the testing of continuous modelling software. Where possible, the testing has been conducted by following the methodology outlined in the SSfM report " Testing Continuous Modelling Software " [1]. Where following this methodology has not been possible, the advice on alternative testing methods in the report [1] has been employed. The problems studied ...

Dengue and Zika, arboviruses are common in Brazil present with similar clinical symptoms making specific diagnoses difficult. Therefore, a Duplex One-step RT-PCR method for dengue zika virus was developed validated vitro silico, based on the dengue's NS1 region zika's Envelope region.

We have developed a simple, labor-saving, inexpensive and rapid SNP genotyping method that directly uses a human hair root as the template. This single-tube genotyping method was used to successfully and reliably genotype the ADH1B and ALDH2 polymorphisms using a hair root (without DNA isolation) and the polymerase chain reaction (PCR) enzyme kit KOD FX. Since the DNA extraction step was elimin...

Ciliates play important roles as prey and predators in ecosystems. Changes in the ciliate community can affect the composition and population of microfauna and microflora in ecosystems. To investigate the structure of ciliate communities, we developed a nested PCR-DGGE method, which combines a universal eukaryotic-specific primer set in the first PCR step with a ciliate-specific primer set in t...

In the present study a protocol of in situ reverse transcriptase-nested polymerase chain reaction (in situ RT-nested PCR) was examined based on the following modifications. (i) To exclude false positive signals caused by "DNA repair mechanisms" and "endogenous priming", a two-step PCR was applied after reverse transcription. The first step was performed in the presence of extrinsic primers and ...
