Insulin-like growth factor 1 (IGF1) is a mediator of the effects hormone and polymorphism in IGF1 gene reported to affect fat deposition some livestock species. In this study, nucleotide sequence variation three regions ovine (part 5' flanking region, exon 3 4 region) was investigated 848 New Zealand Romney lambs using PCR-single strand conformation (SSCP) analyses ascertain if single polymorph...
The use of capillary electrophoresis (CE) in a polymer network for single-strand conformation polymorphism (SSCP) is investigated. SSCP is a method to detect DNA point mutations, essential in the diagnosis of several diseases. The PCR (polymerase chain reaction) amplified p53 gene, a tumour suppressor gene known to be frequently mutated in malignant cells, was subjected to CE analysis. Two sing...
A non-isotopic single-strand conformation polymorphism ('cold' SSCP) technique has been assessed for the analysis of sequence variability in the expansion segment 5 (ES5) of domain IV and the D3 domain of nuclear ribosomal DNA within and/or among isolates and individual muscle (first-stage) larvae representing all currently recognized species/genotypes of Trichinella. Data are consistent with t...
Single-strand conformation polymorphism (SSCP) analysis of ribosomal DNA (rDNA) was investigated for rapid differentiation of phenotypically similar yeast species. Sensitive tests indicated that some yeast strains with one, most strains with two, and all strains with three or more nucleotide differences in the internal transcribed spacer 1 (ITS1) or ITS2 region could be distinguished by PCR SSC...
Mycoplasma pneumoniae is usually susceptible to macrolides, but macrolide-resistant strains have been found frequently in recent years. Mutations in domain V of the 23S rRNA gene of M. pneumoniae interfere with the binding of macrolides to rRNA and mediate macrolide resistance. In this study, we developed a rapid and inexpensive method that combines nested PCR (nPCR), single-strand conformation...
Department of Human Genetics, Faculty of Medicine, University of Stellenbosch, Tygerberg, 7505, South Africa The ability to detect mutations in individuals and the subsequent DNA diagnosis of genetic diseases are becoming increasingly important for the researcher and diagnostician. Single-base substitutions (80-90%) can be detected by single-strand conformation polymorphism (SSCP) (1) or hetero...
Maturity-onset diabetes of the young (MODY) is a form of NIDDM characterized by an early age of onset and autosomal-dominant inheritance (1). So far, three MODY-causing genes have been identified; namely, the hepatocyte nuclear factor4a (HNF-4a)/M0DYl on chromosome 20q, the glucokinase/M0DY2 on chromosome 7p, and the HNFla/M0DY3 on chromosome 12 q (2-4). The identification of the MODY genes has...
Single-stranded conformational polymorphism (SSCP) analysis is useful for mutation detection and polymorphism identification. To realize high-throughput SSCP analysis using a high-intensity electric field, the gel temperature must be well-controlled. We have developed an electrophoretic system having a pair of glass plates with an efficient temperature-controlling apparatus on each side of the ...
Evaluation of Bone Morphogenetic Protein-4 gene polymorphism for growth traits in Indian goat breeds
The genetic improvement of production traits can be made through marker assisted selection using a candidategene approach. Bone morphogenetic proteins (BMPs) are multifunctional growth factors that belong to thetransforming factor b (TGF-b) superfamily. This study aimed detect the polymorphism BMP-4in different goat breeds by polymerase chain reaction-single strand confirmational (PCR-SSCP) and...
BACKGROUND We developed a rapid, precise, and accurate microarray-based method that uses a three-dimensional platform for detection of mutations. METHODS We used the PamChip microarray to detect mutations in codons 12 and 13 of K-ras in 15 cell lines and 81 gastric or colorectal cancer tissues. Fluorescein isothiocyanate-labeled PCR products were analyzed with the microarray. We confirmed the...
