Using the single-strand conformational polymorphism technique, we have screened 66 malignant ovarian tumors for p53 mutation in exons 5 to 8. Thirty-four of the tumors demonstrated a single-strand conformational polymorphism band shift in this region of the gene, including 6 in exon 5, 7 in exon 6, 12 in exon 7, and 10 in exon 8 (one of the tumors showed a shift for exons 7 and 8). All of the s...

Single-strand conformational polymorphism and denaturing gel electrophoresis were used to screen for mutations in the protoporphyrinogen oxidase gene (PPOX) of three patients with clinically and biochemically proven variegate porphyria in order to select genomic regions for specific DNA sequence analysis. Two previously undescribed mutations were identified: PPOX1423-1426-delATCT and PPOX2272in...

The myogenic factors (MYF) 5 gene has been reported to contribute to muscle growth and development, therefore they are considered as candidate genes for growth and meat quality related traits. The MYF5 gene is expressed during proliferation of myoblasts and comprises 3 exons. To ascertain whether there is any variation in the camel MYF5 gene, we have used a polymerase chain reaction-single stra...

Molecular genetics selection on individual genes is a promising method to genetically improve economically important traits in livestock. The insulin like growth factor-I (IGF-I) gene may play important roles in growth of multiple tissues, including muscle cells, cartilage and bone. The objectives of the present study were the estimate the haplotype frequencies of the IGF-I gene polymorphisms i...

b ackground: 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 poly- morphism-polymerase chain reaction (sscp-pcr). m ethods: during 2008 to 2010 fifty samples were collected from iranian patients with p. vivax in hormozgan province, southern iran. all of the samples were...

introduction: congenital long qt syndrome (lqts) is a cardiac disorder characterized by qt interval prolongation at basal ecg. different lqts genes encode ion channel subunits or proteins involved in regulating cardiac ionic currents. long qt syndrome type 6 (lqt6) is caused by mutation in the kcne2 gene. our research aimed to analyze genetic variants of kcne2 gene causing the disease in irania...

Three-hundred ninety-two adult Dermacentor variabilis were collected from six Maryland counties during the spring, summer, and fall of 2002. Infection prevalence for spotted fever group Rickettsia was 3.8%, as determined by polymerase chain reaction. Single strand conformational polymorphism (SSCP) analysis followed by sequencing indicated that all infections represented a single rickettsial ta...
