Materials and methods: The present study identified the abnormal hemoglobins associated with the beta-globin gene using different molecular genetic techniques following high performance liquid chromatography (HPLC) results. We studied 972 postnatal and 361 prenatal cases (total: 1333 cases, 2666 chromosomes) with the disorder from 1998 up to July 2008. DNA extraction from peripheral blood, chor...

Important losses in poplar productivity occur because of susceptibility to microbial pathogens. To enhance disease resistance in susceptible genotypes, the gene coding for D4E1, a synthetic antimicrobial peptide consisting of 17 amino acid residues, was introduced into poplar (Populus tremula L. x Populus alba L.) via Agrobacterium-mediated transformation. Four kanamycin-resistant transformants...

Submitted 24 Sep 2015; Accepted 17 Oct 2015; Published 20 Dec 2015 Cystic fibrosis (CF) is an autosomal recessive disease caused by a wide spectrum of mutations in the gene encoding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. These mutations that correlate with different phenotypes, vary in their frequency and distribution among different populations. In this stu...

Three methods were compared for the detection of prunus necrotic ringspot virus in herbaceous and woody plants: DAS-ELISA, nonisotopic dot-blot hybridization and reverse transcriptional polymerase chain reaction (RT-PCR). When purified virus preparations were used, the detection limit of the RT-PCR technique was 1·28 pg mL whereas nonisotopic molecular hybridization and DAS-ELISA allowed detect...

A a Abstract. Human leukocyte antigen HLA-B51 is the most strongly associated gene with Behçet disease (BD) in different ethnic populations. We analyze the influence of HLA-B alleles in BD predisposition in Moroccan population and its association with clinical manifestations. The HLA-B phenotype frequencies were analyzed by serologic HLA class I typing and by polymerase chain reaction sequence-...

Mutant-enriched PCR and reverse dot blot hybridization in microplates were applied for examining K-ras status in stools and tissue samples from patients with pancreatic tumors and chronic pancreatitis. In tissue samples, K-ras mutations were found in 32 of 35 cases of ductal adenocarcinoma, in 5 of 7 periampullary cancers, in 1 cystadenocarcinoma, and in 3 of 5 patients with chronic pancreatiti...

BACKGROUND A variety of approaches to understanding protein structure and function require production of recombinant protein. Mammalian based expression systems have advantages over bacterial systems for certain classes of protein but can be slower and more laborious. Thus the availability of a simple system for production and rapid screening of constructs or conditions for mammalian expression...

Dot blot and transblot enzyme-linked immunosorbent assays (e.l.i.s.a.) are described which provide sensitive non-radioactive methods for screening Z-DNA-specific antisera and for detecting Z-DNA in polydeoxyribonucleotides and supercoiled plasmids. In the alkaline phosphatase dot blot e.l.i.s.a., Z-DNA, Br-poly(dG-dC).poly(dG-dC), or B-DNA, poly(dG-dC).poly(dG-dC), poly(dA-dT).poly(dA-dT), Br-p...
