Mismatch Formation In Solution And On Dna Microarrays: How

Di: Ava

In molecular biology, formamide (FA) is a commonly used denaturing agent for DNA. Although its influence on DNA duplex stability in solution is well established, little is known about immobilized DNA on microarrays. We measured thermal denaturation curves for oligonucleotides immobilized by two standard protocols: thiol self-assembling and pyrrole Mismatch formation in solution and on DNA microarrays: how modified nucleosides can overcome shortcomings of imperfect hybridization caused by oligonucleotide composition and base pairing.

DNA/DNA duplex formation is the basic mechanism that is used in genome tiling arrays and SNP arrays manufactured by Affymetrix. However, detailed knowledge of the physical process is still lacking. In this study, we show a free energy analysis of Mismatch formation in solution and on DNA microarrays: how modified nucleosides can overcome shortcomings of imperfect hybridization caused by oligonucleotide composition and base pairing.

Abstract In this article it is shown how optimized and dedicated microarray experiments can be used to study the thermodynamics of DNA hybridization for a large number of different conformations in a highly parallel fashion. In particular, free energy penalties for mismatches are obtained in two independent ways and are shown to be correlated with values from melting

Abstract Hybridization intensities of 30 distinct short duplex DNAs measured on spotted microarrays, were directly compared with thermodynamic stabilities measured in solution. DNA sequences were designed to promote formation of perfect match, or hybrid duplexes containing tandem mismatches. Thermodynamic parameters DeltaH degrees , DeltaS degrees and

Although the basic principle behind DNA microarrays is similar to that of traditional hybridizations using nitrocellulose or nylon membranes (Southern et al., 1999) the probe-target appellations are reversed in microarrays. In microarrays, the known testing DNA (probe) is immobilized on the chip surface and the unknown nucleic acid being queried, is labeled and Mismatch formation in solution and on DNA microarrays: how modified nucleosides can overcome shortcomings of imperfect hybridization caused by oligonucleotide composition and base pairing.

Previously, I introduced the DNA microarray technology and described the principle behind it: hybridization between the nucleic acid sequence from the biological samples being examined and a synthetic probe immobilized and spatially arrayed on a solid surface, the microarray. In this article, I will explain how these probes are designed and positioned on the
