Myostatin, a transforming growth factor-beta superfamily member, has been well documented as a negative regulator of muscle growth and development. Myostatin, which has 376 amino acids, is synthesized as a precursor protein. Polymorphism of the myostatin gene in Makoei sheep was investigated by PCR and single-strand conformation polymorphism technique (SSCP). Genomic DNA of 92 sheep was is...
BACKGROUND The main goal of present study was to detect polymorphism in MSP-1 gene which is a major blood stage candidate for vaccine in Plasmodium vivax by Single Strand Conformational Polymorphism-Polymerase Chain Reaction (SSCP-PCR). METHODS During 2008 to 2010 fifty samples were collected from Iranian patients with P. vivax in Hormozgan Province, southern Iran. All of the samples were det...
AIM Development of a nested-PCR single strand conformation polymorphism (SSCP) assay targeting the 16S rRNA genes of the Staphylococcus genus, to monitor staphylococci in cheese. METHODS AND RESULTS New primer sets to specifically amplify 16S rDNA of staphylococci were designed to be used in a nested-PCR SSCP assay. The method was efficient in discriminating the staphylococcal species most fr...
The PCR single strand conformational polymorphism (PCR-SSCP) technique described to identify mutants of the SHV beta-lactamases was extended to identify an SHV-7 type beta-lactamase. This was found in a strain of Klebsiella pneumoniae, the first recorded isolate in the UK to produce this type of enzyme. We also demonstrate that PCR-SSCP can be used to identify more than one SHV beta-lactamase g...
Arbitrarily primed PCR methods (1), including RAPD (2), generate a reproducible fingerprint of DNA products from complex nucleic acids. Differences detected between fingerprints derived from different genomes have been used extensively as polymorphisms in genetic mapping (e.g., 3). Various strategies can be used to maximize the number of polymorphisms that are scored in each fingerprinting expe...
This study was conducted to investigate the association of Gonadotropin-Releasing Hormone Receptor (GnRHR) gene with growth traits in Awassi (n= 123) and Karakul 78) sheep. Starting from birth-day 12 months age, several were investigated, namely body weight length, wither rump height, chest, abdominal circumferences. Four fragments designed amplify three exons GnRHR gene, P1 P2 for exon 1, P3 2...
Background and objectives: DNA hyper-methylation is an important aspect involved in carcinogenesis cancer progression, which affects mainly CpG islands of causes inactivation tumour suppressor genes. Therefore hypermethylation status the genomic both transformed cancerous cell lines carcinogen-induced lung was ascertained by analysis expressions certain major specific The other objective to exa...
Cultivation-independent analyses were carried out to compare the bacterial community structure found in the rhizospheres of a transplastomic tobacco plant carrying the antibiotic resistance marker-gene aadA and its nonengineered parental line. PCRand reverse transcriptase PCR-amplifications of 16S rRNA and their corresponding genes were carried out with primers targeting the domain Bacteria. Th...
amide gel electrophoresis (PAGE) on a 180× 160× 1.5-mm 10% polyacrylamide gel. The separated DNA strands were subsequently visualized by staining with either EtdBr or silver (2). Separation of the DNA strands before electrophoresis using streptavidin paramagnetic beads consistently yielded single-stranded products upon SSCP analysis (Figure 1). Treatment of DNA strands with S1 nuclease before S...
Bacteremia continues to result in significant morbidity and mortality, particularly in patients who are immunocompromised. Currently, patients with suspected bacteremia are empirically administered broad-spectrum antibiotics, as definitive diagnosis relies upon the use of blood cultures, which impose significant delays in and limitations to pathogen identification. To address the limitations of...
