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 aim was to detect the presence of polymorphisms at exons 1, 2, 3 and 4 of the Spi2 gene, and evaluate a possible association between them and recurrent airway obstruction (RAO) or inflammatory airway disease (IAD) in thoroughbred horses, through single-strand conformational-polymorphism (SSCP) screening. Although polymorphism was not detected in exons 1, 2 and 3, three alleles and six genot...

Detection and identification of point mutations in genomic DNA has proven increasingly important in biomedical research. A variety of methods for the analysis of single base substitutions have been proposed among which Single Strand Conformational Polymorphism (SSCP) quickly gained success due to its simplicity. In this work we present an analytical on-line tool which combines the ease of solid...

Background: Histones are replaced by protamines to condensate and package DNA into the sperm head during mammalian spermatogenesis. Protamine genes defects have been reported to cause sperm DNA damage and male infertility. In this study relationship among some protamines genes family SNPs include PRM1 (C321A), PRM2 (C248T) and TNP2 (T1019C), (G1272C), (G del in 1036 and 1046 bp) were studied in...

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...
