This site contains the dataset used for the following paper.

Li Liao and Zhongwei Li, "Correlation between gene silencing activity and structural features of antisense oligodeoxynucleotides and target RNA", In Silico Biology, 7:0036, 2007.

antisense_oligo_database contains a list of antisense oiglo sequences and their corresponding actitivity.
antisense_target_rna.fa contains a list of RNA sequences in fasta format.

These two files were downloaded from http://antisense.genetics.utah.edu and details about the data are reported in Giddings et al (2000) Bioinformatics 16:843-844.
