Array-based comparative genomic hybridization is a high resolution method for measuring chromosomal copy number changes. Here we present a validated protocol using in-house spotted oligonucleotide libraries for array comparative genomic hybridization (CGH). This oligo array CGH platform yields reproducible results and is capable of detecting single copy gains, multi-copy amplifications as well ...
High-density functional gene arrays have become a powerful tool for environmental microbial detection and characterization. However, microarray data normalization and comparison for this type of microarray remain a challenge in environmental microbiology studies because some commonly used normalization methods (e.g., genomic DNA) for the study of pure cultures are not applicable. In this study,...
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...
In previous studies, the single selenonucleoside component of a selenium-containing tRNAGlu isolated from Clostridium sticklandii has been shown to be 5-methyl-aminomethyl-2-selenouridine. Here, we show that this selenonucleoside is most likely located at the "wobble" position of the anticodon of the clostridial seleno-tRNAGlu. Nuclease T1 digestion of this seleno-tRNAGlu generated one major se...
The availability of sequenced eukaryotic genomes and commercial oligonucleotide tiling microarrays has enabled many genomics applications. Different from expression microarrays, tiling microarrays have probes that cover the entire genome or contigs of the genome in an unbiased fashion. Currently three commercial sources provide tiling microarrays with different probe lengths and spacing, and ar...
A naphthyridine dimer that binds specifically to G-G mismatches has been used to induce hairpin formation in oligonucleotides immobilized onto chemically modified gold surfaces. Surface plasmon resonance (SPR) imaging measurements of DNA microarrays were used to demonstrate that binding of the naphthyridine dimer to G-G mismatches within the stem portion of an immobilized 42-mer oligonucleotide...
