Optimized sensitivity of allele-specific PCR for prenatal typing of human platelet alloantigen single nucleotide polymorphisms.

PCR using sequence-specific primers (PCR-SSP) is widely employed for the genotyping of single nucleotide polymorphisms (SNPs) in both routine diagnosis and medical research. The human platelet alloantigens (HPAs) represent SNPs in platelet-specific glycoproteins, and HPA-1, -2, -3, and -5 are the most relevant in immunohematology. In most protocols, the respective HPA-SNPs are analyzed in allel...

A Microfluidic Device for Detection of Single Nucleotide Polymorphisms by Allele Specific Single Base Extension

We present a microfluidic device with integrated temperature sensors and heaters for single nucleotide polymorphism (SNP) detection. The allele specific primer is immediately annealed next to the polymorphic site, and extended by a single base. The extension product is then purified by solid phase capture, and subsequently released via chemical cleavage. After desalting, the released product is...

Accuracy of genotyping for single nucleotide polymorphisms by a microarray-based single nucleotide polymorphism typing method involving hybridization of short allele-specific oligonucleotides.

Advances in technologies for identifying genetic polymorphisms rapidly and accurately will dramatically accelerate the discovery of disease-related genes. Among a variety of newly described methods for rapid typing of single-nucleotide polymorphisms (SNPs), gene detection using DNA microarrays is gradually achieving widespread use. This method involves the use of short (11- to 13-mer) allele-sp...

Fluorescent allele-specific PCR (FAS-PCR) improves the reliability of single nucleotide polymorphism screening.

The detection of single nucleotide polymorphisms (SNPs) is becoming increasingly important in both the evaluation of candidate gene polymorphisms and fine mapping studies (4,7). Many techniques exist for the detection of SNPs within random sequences, such as single-strand conformation polymorphism (SSCP) (5,6), heteroduplex analysis and direct sequencing, but few techniques specifically identif...

Split hybridisation probes for electrochemical typing of single-nucleotide polymorphisms.

This paper describes the development of a highly selective single-nucleotide polymorphisms (SNPs) typing method based on the use of split hybridisation probes and demonstrates the concept through the electrochemical analysis of single-base mutations in actual patient samples. The requirement that two probes hybridised adjacent to one another to allow for stabilisation (via base-stacking) and bi...
