It incorporates important information on siRNA sequence, chemical modification, their number and respective position, structure, simplified molecular input line entry system canonical (SMILES), efficacy of modified siRNA, target gene, cell line, experimental methods, reference etc. siRNAmod browsing option helps user to surf via these five categories: i) modification in sense strand, ii) position of modification in sense strand, iii) modification in antisense strand, iv) position of modification in antisense strand and v) reference.

In silico resources developed to facilitate scientific community fighting against deadly virus EBOLA. EbolaVCR enlists possible vaccine candidates, therapeutic siRNAs and other related resources. Firstly, we predicted and identified experimentally validated epitopes in each of the antigens/proteins of the five known ebolaviruses. Secondly, we generated all the possible overlapping 9mer peptides from the proteins of ebolaviruses. Thirdly, conserved peptides across all the five ebolaviruses (four human pathogenic species) with no identical sequence in the human proteome, based on 1000 Genomes project, were identified. Finally, we identified peptide or epitope-based vaccine candidates that could activate both the B- and T-cell arms of the immune system. In addition, we also identified efficacious siRNAs against the mRNA transcriptome (absent in human transcriptome) of all the five ebolaviruses.

A manually curated database of HIV inhibiting siRNAs that provides comprehensive information about each siRNA or shRNA. HIVsirDB structure contains sixteen fields including siRNA sequence, HIV strain, targeted genome region, efficacy and conservation of target sequences. Users can explore information in user friendly manner using the search and browsing facility. HIVsirDB is useful to experimentalists in deciding the highly potent siRNAs targeting the most susceptible target site in HIV genome and its experimental procedure to suppress HIV infection.

Aims to provide a resource for researchers looking for validated siRNAs against target genes, with an emphasis on genes potentially involved in cancer. The MIT/ICBP siRNA database has basic information regarding submitted sequences. In addition, we provide links to more annotated information available through NCBI's probe database.

Offers information about 2 million products, submitted by a reagent provider partners. All reagents are organized according to genes, species, reagent types (antibodies, recombinant proteins, ELISA, siRNA, cDNA clones, biochemicals, and others). VAD is developed with manually curation antibody applications from selected formal publications. Review articles for antibodies, based on VAD, and for commonly used reagents are freely available.

Allows researchers worldwide access to information as well as allow purchase of the constructs. RNAi Codex holds data from the Hannon–Elledge shRNA library and allows the use of biologist-friendly gene names to access information on shRNA constructs that can silence the gene of interest. It is designed to hold user-contributed annotations and publications for each construct, as and when such data become available.

Provides sequences of published functional siRNA molecules targeting human genes and important technical details of the corresponding gene silencing experiments, including the mode of siRNA generation, recipient cell lines, transfection reagents and procedures and direct links to published references (PubMed). To retrieve functional siRNAs sequences for a specific gene, the human siRNA database can be searched for UniGene cluster IDs, gene names, RefSeq accession numbers and target gene descriptions.

Provides a gene-centric view of siRNA experimental data, including siRNAs of known efficacy and siRNAs predicted to be of high efficacy by a combination of methods. Linked to these sequences is information such as siRNA thermodynamic properties and the potential for sequence-specific off-target effects. The database interface was designed with the experimental user group as the primary target audience. The user interface is gene-centric, allowing the user to search by nucleotide accession number, free text, sequence or by viewing the list of genes with verified siRNAs.

Hosts off-target information. SeedSeq is an online repository that aims to provide a data source for design, validation of small-interfering RNA (siRNA) libraries, and experiments. The particularity of this database is that it furnishes collection of human mRNA transcripts and their siRNA reagents off-target predictions in GenBank format. Its design permits users to determine which transcripts are the most sensitive for being off-target.
