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...

The inability to distinguish failures of treatment of Plasmodium falciparum infection from new infections is an important impediment to the evaluation of antimalarial drugs. On the basis of a pilot study utilizing polymerase chain reaction (PCR) single-strand conformational polymorphism (SSCP) analysis to genotype P. falciparum isolates, we sought to confirm that PCR SSCP analysis could reliabl...

Aim-To correlate immunohistochemical staining with single strand conformation polymorphism (SSCP) analysis of the p53 gene in colorectal cancer in order to understand how the findings provided by the two techniques complement each other in defining p53 functional status.Methods-Frozen tumour tissue from 94 patients with colorectal cancer was studied for p53 protein accumulation and gene mutatio...

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,...

OBJECTIVE To rapidly detect rifampin resistance in Mycobacterium tuberculosis isolates causing meningitis in northeast Iran. METHODS This study presents the results of a polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) analysis for the evaluation of rifampin resistance directly from the CSF of 47 patients strongly suspicious to have tuberculosis meningitis in Emam ...
