A rapid and simple method, termed multiplex mutagenically separated PCR (MS-PCR), was developed to detect several molecular defects in the hemoglobin gene in one PCR. This technique, in which different-size allele-specific primers were used, specifically amplified both normal and mutant alleles of the globin gene in the same reaction. Subsequent gel electrophoresis showed at least one of the tw...

Acetes chinensis is an economically important shrimp that belongs to the Sergestidae family; following fermentation, A. chinensis' economic value, however, is low in China, and much of the catch in China is exported to Korea at a low price, thus leading to potential false labeling. For this reason, we developed a simple method to identify A. chinensis' origin using allele-specific polymerase ch...

background: salmonella enterica serovar typhi, as causative agent of typhoid fever, is one of the most important endemic pathogens. non-typhoidal salmonella serovars, including typhimurium , infantis , and enteritidis are amongst the most prevalent serotypes worldwide and in developing areas such as iran. the aim of this study was to apply a uniplex pcr for rapid detection of salmonella spp., a...

We have developed a new method for high-throughput genotyping of single nucleotide polymorphisms (SNPs). The technique involves PCR amplification of genomic DNA with two tailed allele-specific primers that introduce priming sites for universal energy-transfer-labeled primers. The output of red and green light is conveniently scored using a fluorescence plate reader. The new method, which was va...

the pituitary-specific transcription factor (pit1) gene is responsible for pituitary development and hormone secreting gene expression in mammals. pit-1 is studied as a candidate genetic marker for growth, carcass and also for milk yield traits. in dairy farm animals, the principal goal of the selection is the improvement of milk yield and composition. the genes of milk proteins and hormones ar...

The focus on small isolated populations provides important insights into the factors affecting the distribution of inheritable traits. Here, we present a report on the distribution of the CCR5 ∆32 mutation in the so far unstudied innate Sudanese population of Shagia people. The genetic material (buccal swabs) was collected from 125 individuals living in three African villages, Abu Haraz, Shibab...

We report the development of universal primers for the reverse-transcription polymerase chain reaction (RT-PCR) amplification and nucleotide sequence analysis of actin cDNAs from taxonomically diverse mosquito species. Primers specific to conserved regions of the invertebrate actin-1 gene were designed after actin cDNA sequences of Anopheles gambiae, Bombyx mori, Drosophila melanogaster, and Ca...

irritable bowel syndrome (ibs) is a functional gastrointestinal disorder, characterized by recurrent abdominal pain and altered bowel habits. this study was performed to investigate the important role of interleukin-12 (il-12) in intestinal inflammation. for this study seventy one patients with ibs and 140 controls were investigated. the allele and genotype frequencies of il-12 c(-1188)a were d...

there are several known and unknown factors for unexplained recurrent spontaneous abortion (ursa). among them, complement regulatory protein cd46 plays a pivotal role in preventing uncontrolled activation of complement and successful continuation of pregnancy. we aimed in this study to investigate the possible association of cd46 ivs1-1724 c>g polymorphism with rsa in iranian women. 141 women w...
