متن کاملMutation Detection by Single Strand Conformation Polymorphism and Heteroduplex Analysis
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...
متن کاملDetermination of apolipoprotein E genotypes by single-strand conformational polymorphism.
We used single-strand conformational polymorphism (SSCP) to determine apolipoprotein E (Apo E) genotypes in 47 individuals. A 295-base-pair (bp) DNA fragment coding for amino acid residues 80-178 of the Apo E protein gave distinct patterns for the three alleles. When we used SSCP to determine the Apo E polymorphism of five individuals whose phenotyping results differed from those of genotyping,...
متن کاملIntraspecies polymorphism of Cryptosporidium parvum revealed by PCR-restriction fragment length polymorphism (RFLP) and RFLP-single-strand conformational polymorphism analyses.
A glycoprotein (Cpgp40/15)-encoding gene of Cryptosporidium parvum was analyzed to reveal intraspecies polymorphism within C. parvum isolates. Forty-one isolates were collected from different geographical origins (Japan, Italy, and Nepal) and hosts (humans, calves, and a goat). These isolates were characterized by means of DNA sequencing, PCR-restriction fragment length polymorphism (PCR-RFLP),...
متن کاملAnalysis of p53 gene mutations in keloids using polymerase chain reaction-based single-strand conformational polymorphism and DNA sequencing.
BACKGROUND Keloids are the result of a dysregulated wound healing process. They are characterized by the formation of excess scar tissue that proliferates beyond the boundaries of the original wound. Somatic mutations of p53 have been implicated as causal events in up to 50% of all human malignancies. In addition, p53 has been shown to play an important role in controlling cell proliferation an...
