Single strand conformation polymorphism (SSCP) analysis discriminated three mtDNA haplotypes in the greenbug, Schizaphis graminum (Rondani) (Homoptera: Aphididae), previously identified by sequencing a 1.0–1.2 kb portion of the cytochrome oxidase subunit I (COI) gene. Neighborjoining, maximum parsimony, and maximum likelihood analysis of a 150 b portion of the original 1.2 kb fragment of the CO...

The purposes of this study were to investigate single strand conformation polymorphisms (SSCP) in the D-loop region of pig mitochondrial DNA (mtDNA) and to determinate their association with the reproductive traits of meishan pigs. A total of four types of band patterns, designed SSCP band pattern A, B, C and D, were identified. A type of SSCP band pattern was present in all European-American b...

Single strand conformation polymorphism (SSCP) and heteroduplex analysis (HDA) are two of the most popular electrophoresis-based mutation detection methods. Coupled to DNA amplification of the sequence to be analyzed, these techniques have become the methods of choice for a number of molecular diagnostic laboratories. This can be explained mainly by the numerous advantages, namely their technic...

The Nramp1 (Natural resistances macrophage protein1) gene or recently renamed Slc11a1 (solute carrier family 11 member1) is a member of a large family of genes coding for metal ion-transporting proteins. Nramp1 gene plays a critical role in innate immunity favoring bacterial killing by macrophages in addition to its influence on adaptative immunity. The aim of the present investigation was to i...

Polymorphism within the promoter region of bovine thyroglobulin has been reported to be associated with milk and meat quality. In this study, we investigated the genetic variation within thyroglobulin promoter region of swamp and riverine buffaloes using PCR-SSCP technique and sequencing, and also analyzing association of polymorphism with the milk production traits. The study revealed four con...

BACKGROUND Establishment of a sensitive, reliable and non-invasive method for the diagnosis of early-stage colorectal cancer is necessary, because colorectal cancer can be cured surgically if diagnosed early. The aim of the present study was to evaluate the feasibility of using PCR-SSCP (polymerase chain reaction-single strand conformation polymorphism) analysis of the DNA extracted from the co...

We used the recently described technique of single-stranded conformation-polymorphism (SSCP) analysis to examine the insulin-receptor locus. First, the ability of the method to detect known mutations and polymorphisms in the insulin-receptor coding sequence was assessed. Regions of the insulin-receptor sequence containing 16 different nucleotide changes, 9 in patient genomic DNA and 7 as cloned...

SSCP (single-strand conformational polymorphism) is used widely in the field of human biomedicine, but its potential as a population genetics tool for the recovery of nuclear gene genealogies remains to be realized. We describe and illustrate a use for SSCP in the physical isolation of nuclear haplotypes that circumvents several difficulties associated with more conventional cloning procedures....

Secreted phosphoprotein 1 (SPP1) is an acidic, phosphorylated glycoprotein found in fluids including milk and involved development of mammary gland exhibits impact on composition yield. The aim study was to reveal SPP1 gene polymorphisms association with traits Gaolao cattle. Blood collected from 280 cows test day recorded. SPP1G1-BsrI locus intron-IV polymorphic frequency TT genotype 0.99 CT 0...
