Single strand conformation polymorphism (SSCP) is a reproducible, rapid and quite simple method for the detection of deletions/insertions/rearrangements in polymerase chain reaction amplified DNA. All the details for the use of PCR-SSCP are presented in the direction of genetic diseases (beta-thalassaemia, cystic fibrosis), optimum gel conditions, sensitivity and the latest modifications of the...

Single-strand-conformation polymorphism (SSCP) of DNA, a method widely used in mutation analysis, was adapted to the analysis and differentiation of cultivated pure-culture soil microorganisms and noncultivated rhizosphere microbial communities. A fragment (approximately 400 bp) of the bacterial 16S rRNA gene (V-4 and V-5 regions) was amplified by PCR with universal primers, with one primer pho...

Genotypes of Iranian Zel sheep for Calpastatin(CAST) locus were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) methods and for Calpain(CAPN) locus by PCR-SSCP. Blood samples were collected from 200 purebred Zel sheep of Zel Breeding Station located in Golestan province i...

The use of polymerase chain reaction-single-stranded conformational polymorphism (PCR-SSCP) to study rpoB gene mutations in rifampin-resistant (RIFr) Mycobacterium tuberculosis has yielded contradictory results. To determine the sensitivity of this method, we analyzed 35 RIFr strains and 11 rifampin-susceptible (RIFs) strains, using the DNA sequencing of the core region of rpoB for comparison. ...

BACKGROUND We have previously studied p53 gene mutations in 25 primary gastric cancer tissues by polymerase chain reaction single-strand conformation polymorphism (PCR-SSCP) analysis for exon 4-8 and immunohistochemical staining with anti-p53 antibody. In four cases, the discrepancy of the results was observed between the two methods. In one case positive by PCR-SSCP but negative by immunohisto...

PURPOSE Because of the emergence of multidrug-resistant tuberculosis in recent times, the rapid detection of resistance to the first-line anti-tuberculosis drug rifampicin was felt worldwide. Accordingly, this study was conducted to evaluate the diagnostic potential of polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) for checking its utility as a rapid screening test...

The recent achievement of the human genome project has led to the identification of many disease genes in common hereditary conditions, in which patients and their relatives would benefit from genetic diagnosis. This has increased the need for simple, sensitive, and cost effective methods of mutation analysis. However, the “gold standard” of mutation analysis, direct sequencing, is still an exp...
