چکیده

Although widely used, the detection of DNA mutations by the single-strand conformation polymorphism (SSCP) method is often hampered by the need to examine a large set of electrophoretic conditions in order to select the one suited to the DNA sequence under study. We show here that the use of transverse chemical gradient gels allows for a quick and easy optimisation of SSCP analysis, as exemplified on two mutations in exon 2 of the alpha-1-antitrypsin gene.

DNA Polymorphisms at Candidate Gene Loci and Their Relation with Milk Production Traits in Murrah Buffalo (Bubalus bubalis)

DNA polymorphism within diacylglycerol transferase 2 (DGAT2) / monoacyl glycerol transferases 2 (MOGAT2), leptin and butyrophilin genes were analysed using PCR-SSCP in Murrah buffalo. The single strand conformation polymorphism (SSCP) analysis of amplified gene fragment in exon 5 of MOGAT2, exon 3 of leptin and intron 1 of butyrophilin gene revealed different patterns. A, B and C showed the fol...

High resolution single strand conformation polymorphism analysis using formamide and ethidium bromide staining.

Single strand conformation polymorphism (SSCP) analysis using ethidium bromide can be improved by adding formamide as the denaturant. This gives higher resolution than previous SSCP methods; it had 100% sensitivity in the discrimination of 14 PCR samples from two different genes, even for a long fragment close to the upper limit of 250 base pairs. This modified procedure is a rapid, simple, saf...

Genetic Polymorphism at the Growth Hormone Locus in Iranian Talli Goats by Polymerase Chain Reaction-Single Strand Conformation Polymorphism (PCR-SSCP)

The growth hormone gene could be an attractive candidate gene for milk production in goats. Single-strand conformation polymorphism was used to identify polymorphism at the goat growth hormone (gGH) gene. For this purpose, genotyping of 90 Talli goat breeds was performed. Nine conformational patterns were observed in exon 4 of the gGH gene, with frequencies of 27.7% for the homozygous pattern (...

Study of Dopamine Receptor Gene Polymorphisms and Their Association with Growth and Egg Production Traits in West Azerbaijan Native Chicken

The objective of this study was to search for single nucleotide polymorphism (SNP)-type polymorphisms in the dopamine D1 receptor in West Azerbaijani native chicken and look for their association with egg production and body weight traits of chickens by polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP). For this purpose 180 blood samples were taken from nativ...
