  • Zebrafish BLAST server at MGH:

    MGH site provides a BLAST search of a gene or marker of interest to the assembled sequence contigs of the zebrafish genomic shotgun sequence from the Sanger project.

Primers

This service provides "one stop shopping" for picking primers, BLAST of primer sequences for specificity against the latest zebrafish genome sequence, and graphical views of the locations of primers with different confidence levels. All you need is a few clicks. No more cutting and pasting from one website to another. The program flows automatically. Detailed information for use of this program can be found in the "general info" and "help file".

MGH site offers this tool which searches for a supercontig, scaffold, or finished BAC clone by name or accession number, derives all di- and tri- nucleotide repeat sequences in the supercontig, masks the sequence around the repeats for larger zebrafish repetitive sequences and then designs unique sequence primer pairs to amplify the simple sequence repeats. These are potentially polymorphic simple sequence repeats (SSRs) that can be used in genetic mapping/positional cloning projects. This site also offers a tool to search for marker primer pairs by chromosome coordinates (3MB chromosome segments max.)

Microarrays

The Trans-NIH Zebrafish Genome Initiative at Children's Hospital Boston aims to annotate zebrafish genes with human known genes for functional and comparative studies. This website provides a web service for retrieving annotated zebrafish genes represented on Affymetrix Zebrafish Genome Arrays and Roche-NimbleGen Zebrafish Expression Arrays to the research community.

The Norwegian Microarray Consortium offers their array products for academic use to customers world wide. One limitation is oligonucleotide arrays, which cannot provided to users in the US and Japan, due to licensing conditions. A moderate license fee will be added to the base price for oligonucleotide arrays sold to users in the UK, France, Germany, Italy, Austria, Belgium, Sweden, Switzerland, Luxembourg, and The Netherlands.

Compugen array clones are annotated at this site. The GenBank id of genes in the Compugen oligo list can be used to access information from Unigene, Entrez Gene, Gene Ontology, human and mouse HomoloGene, Unigene protein similarities of mouse and human, ZGI index. The gene chromosomal location is also available. The details of the microarray annotation database are published in PLoS Genetics (2005).

cDNA and EST Resources

NIH initiative for production of full length sequences and cDNA clones.
1819 ZGC clones recloned in pENTR223.1 In May 2008, ZGC has added 1819 full length ZGC clones recloned into a Gateway Entry vector (pENTR223.1;) for expression analysis and other applications.
These clones can be found by searching Entrez nucleotide for "NIH_ZGC_36".

The DFCI Zebrafish Gene Index (ZGI) integrates research data from international zebrafish gene research projects and represents a non-redundant view of all zebrafish genes and data on their expression patterns, cellular roles, functions, and evolutionary relationships.

This database consists of 4694 contigs or singletons obtained from ~18000 reads of cDNAs that were isolated from the microdissected otocysts of zebrafish embryos at 20-30 hours postfertilization, following subtraction with a pool of liver cDNAs from adult fishes.

Mutagenesis Projects

  • Targeted mutations using zinc-finger nucleases (ZFNs):

The Lawson and Wolfe labs have compiled resources relating to their recent publication on targeted gene inactivation using ZFNs:
A list of plasmids and strains (available at addgene):

http://lawsonlab.umassmed.edu/PDFs/B1HStart.pdf

An on-line search tool to identify and design library oligos:
http://pgfe.umassmed.edu/ZFPsearch.html

This project seeks to identify, phenotype and distribute a large number of mutant zebrafish lines. Mutations are identified from populations of chemically mutagenised animals using PCR of specific exons followed by re-sequencing. Mutants are analysed for morphological and molecular differences and distributed to the community. This is an open resource and is now open to requests from the community. The Zebrafish Mutation Resource Tracking page lists the mutants generated by the Sanger Zebrafish Mutation Resource and the ZF-HEALTH consortium.

TALENs/CRISPRs

The CRISPR design tool is a web tool crafted to simplify the process of CRISPR guide selection in an input DNA sequence by (i) discovering possible offtargets genome-wide, (ii) highlighting guides with high target specificity, and (iii) flagging guides with numerous or genic offtargets in target genomes.

E-CRISP is a software tool to design and evaluate target sites for use with the Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR) system. The web application uses fast algorithms to identify sgRNA target sequences in any nucleotide sequence for use in CRISPR/Cas mediated genome editing. E-CRISP analyzes target specificity of the putative designs and assesses their genomic context (e.g. exons, transcripts, CpG islands). The design process incorporates different options of how CRISPR constructs can be used in experimental applications

E-TALEN is a web service to design TALENs for introducing knock-out mutations, for endogenous tagging and targeted excision repair. The tool can be used to design TALENs against a single target but also for up to 50 target genes in parallel. E-TALEN guides the user through end-to-end de-novo design process for specific sequences or genomic loci. In addition, it can also be used to evaluate existing TALEN designs.

 Identifies gRNA target sequences from an input sequence and checks for off-target binding.

A TALEN and CRISPR design tool provided by the Mayo Clinic.

CRISPRz is a curated database of validated CRISPR targets in zebrafish maintained by Shawn Burgess' lab at NHGRI/NIH. The database contains target sites from the Burgess lab's large-scale mutagenesis project, as well as those reported in the literature. A search form allows users to search by various identifiers in order to determine if a validated CRISPR target exists for a gene of interest.
