Controlling oligonucleotide surface density in light-directed DNA array fabrication.
Over the past two decades high-density DNA arrays have developed into a central technology for nucleic acid analyses. Important application areas include whole-genome gene expression studies, high throughput analyses of single nucleotide polymorphisms, and, most recently, the determination of binding site specificities for transcription factors and other critical elements involved in gene regul...
متن کاملAlgorithms for high-density oligonucleotide array.
As a global gene expression-monitoring tool, high-density oligonucleotide arrays (HDAs), accelerate biological and drug discovery processes. Computational considerations affect several key issues, from array design and accurate gene expression level determination to various aspects of the biological analysis of cell functions and gene networks. This review highlights recent progress in ideas an...
متن کاملCombinational synthesis of oligonucleotides and assembly fabrication of oligonucleotide array.
In this paper, a simple, reliable and flexible method, which integrated in situ synthesis with the spotting technique, was reported to fabricate oligonucleotide array. Different oligonucleotide sequences are synthesized on their relative code glass slides through combinational chemistry, thus the slides are broken into smaller pieces, in which the same code pieces have the same probe sequences....
متن کاملLight-directed synthesis of high-density oligonucleotide arrays using semiconductor photoresists.
High-density arrays of oligonucleotide probes are proving to be powerful new tools for large-scale DNA and RNA sequence analysis. A method for constructing these arrays, using light-directed DNA synthesis with photo-activatable monomers, can currently achieve densities on the order of 10(6) sequences/cm2. One of the challenges facing this technology is to further increase the volume, complexity...
متن کاملFrom features to expression: High-density oligonucleotide array analysis revisited
One of the most popular tools for large scale gene expression studies are highdensity oligonucleotide (GeneChip R ) arrays. These currently have 16-20 small probes (“features”) for evaluating the transcript abundance of each gene. In addition, each probe is accompanied by a mismatched probe (MM) designed as a control for non-specificity. An algorithm is presented to compute comparative expressi...
