We report optimization of single-strand conformation polymorphism (SSCP) analysis in the presence of polyethylene glycol. The protocol developed separates single-strand conformers in a much shorter time (1-3 h) than conventional SSCP protocols and broadens the applicability of SSCP analysis from 150 to as much as 500 bp of DNA by different percentages of GC content present. We conclude that add...

AIMS The primary objectives of this study were to determine if a single-strand conformation polymorphism (SSCP) analysis can be used for rapid identification of Phytophthora ramorum, an important quarantine plant pathogen worldwide, and to further assess the potential of the SSCP technique as a taxonomic tool for the genus Phytophthora. METHODS AND RESULTS SSCP of ribosomal DNA internal trans...

Capillary electrophoresis single-strand conformation polymorphism (CE-SSCP) is a promising high-throughput tool for profiling complex bioremediation communities, but has not been well characterized with respect to other methods such as denaturing gradient gel electrophoresis (DGGE). The purpose of this study was to compare CE-SSCP with DGGE with respect to: 1) overall representation of the comm...

Single strand conformation polymorphism (SSCP) analysis of the N-ras oncogene was achieved by capillary electrophoresis with a laser-induced fluorescence detector (CE-LIF) using methylcellulose as a molecular sieving agent. The PCR-amplified N-ras oncogene, which is known to have a point mutation at codon 61 in the neuroblastoma, was investigated by CE-LIF combined with SSCP (SSCP-CE-LIF). A mi...

This study detects and defines the patterns of p53 gene mutations in breast cancers. We analyse p53 gene mutations through comparing the results of single-strand-conformation-polymorphism (SSCP) and immunohistochemistry (IHC), and we try to define the differences between the results of SSCP and IHC. Twenty-seven fresh primary breast cancer tissues and eight normal breast tissues were studied. T...

Prompt detection of drug resistance in Mycobacterium tuberculosis is essential for effective control of tuberculosis (TB). We developed a Multi-PCR-SSCP method that detects more than 80% commonly observed isoniazid (INH) and rifampin (RIF) resistance M. tuberculosis in a single assay. The usefulness of the newly developed method was evaluated with 116 clinical isolates of M. tuberculosis. Disti...
