chemokine and chemokine receptors show several variations which may affect resistance to infectious disease. a 32 base pair deletion in the open reading frame of the human ccr5 gene (ccr5?32) results in producing a truncated antigen which fails to be presented on the surface of target cells. ccr5?32 variant is not a functional co receptor for hiv-1 entrance and delay the onset of acquired immun...
The ease and advantages of allelespecific PCR (AS-PCR) for SNP genotyping, along with the difficulty of assay specificity with certain mismatched DNA primers, have been described in prior studies (1–3). More recently, the use of real-time PCR detection formats has been described for one or both alleles of AS-PCR (4–6). These detection enhancement methods do not overcome the inherent difficultie...
Despite significant advances in understanding the molecular basis of sepsis and its associated immunological response, sepsis remains a problem worldwide and is associated with a high mortality. Annually, septic shock, the most severe form of sepsis, causes the death of more than 100 000 people in the USA (3,4). Gram-negative bacteria are the most common pathogens associated with bacterial infe...
The IL28B genotype is a critical determinant of interferon response in patients infected with hepatitis C virus genotype 1. We describe an allele-specific PCR assay for the IL28B genotype. The assay is simple and robust, uses commonly available real-time PCR instrumentation, and is well suited for clinical laboratories offering IL28B genotyping.
We have developed a strategy for multiplex PCR based on PCR suppression. PCR suppression allows DNA target amplification with only one sequence-specific primer per target and a second primer that is common for all targets. Therefore, an n-plex PCR would require only n + 1 primers. We have demonstrated uniform, efficient amplification of targeted sequences in 14-plex PCR. The high specificity of...
Resistance of Bordetella pertussis to erythromycin has been increasingly reported. We developed an allele-specific PCR method for rapid detection of erythromycin-resistant B. pertussis directly from nasopharyngeal (NP) swab samples submitted for diagnostic PCR. Based on the proven association of erythromycin resistance with the A2047G mutation in the 23S rRNA of B. pertussis, four primers, two ...
A simple and rapid method for the analysis of genetic polymorphisms has been developed using allele-specific oligonucleotide arrays bound to glass supports. Allele-specific oligonucleotides are covalently immobilized on glass slides in arrays of 3 mm spots. Genomic DNA is amplified by PCR using one fluorescently tagged primer oligonucleotide and one biotinylated primer oligonucleotide. The two ...
