OligoArray is free software that computes gene specific oligonucleotides for genome-scale oligonucleotide microarray construction. A database of pre-designed oligonucleotide microarray probes for organisms with a fully sequenced genome can be found at http://berry.engin.umich.edu/oligoarraydb/index.html
Server for computing small interfering RNA (siRNA) sequences which are best suited for mammalian RNA interference (RNAi). The site accepts a sequence as input and returns a list of siRNA candidates.
Twinscan is a system for predicting gene-structure in eukaryotic genomic sequences. In order to make its predictions, Twinscan combines the information from predicted coding regions and splice sites with conserservation measurements between the target sequence and sequences from a closely related genome. Currently sequences from mammalian genomes, and those of Arabidopsis thaliana, C. elegans, C. briggsae and strains JEC21 and H99 of Cryptococcus neoformans can be processed using Twinscan.
