NASC's International Affymetrix Service

About NASC's International transcriptomics service

• Any available species (e.g. Human, yeast, Brachypodium, tobacco, bovine, Brassica).
  See a complete list on the Array Gene Chips collection page.
• Any consortium chip (user supplies the chip and definition files).
• Any kind of experiment (e.g. SNP chips, tiling chips - not just gene expression).
  
  
• +PLUS+ a range of 'unavailable' chips
  We have developed open source and free Xspecies software and techniques that can be (examples) used to perform GeneChip transcriptomics experiments on species for which no current Affymetrix chip exists (e.g. Guinea pig, Bison, Horse, Tea, Coffee, Aloe, Oil palm etc...)

If you have any questions, please contact our Affymetrix team at affy@arabidopsis.info.

The Affymetrix service

 

Customers do not need to contact NASC before preparing samples although we will offer advice including hints on how to prepare samples and requirements (concentrations, etc.).

See a complete list of available species on the Array Gene Chips page.

Prices now £350 (€388*, $524*)
*_{approx. exchange rate [21 Mar 2010], prices are charged in pounds. Please add local tax}

Service Procedure

All species / users:

Order the specific type and number of Affymetrix chips that you require from our Affymetrix chip collection page. During the ordering process you will be required to fill in an application form describing your samples and experiment details.

Arabidopsis users only:

Before sending your samples fill in a sample submission form for each of your samples.

Then send your samples

QC procedures

We will email you if the samples fail any of our quality control steps.

Data is sent on CD or DVD and in special cases can be FTP'd from our server.

Plant data only:

Will be made available through NASCArrays after the confidentiality period has expired. From here it can be picked up by GenevestigATor, MapMan and other meta analysis centres.

We prepare and donate the data in your name to GEO and ArrayExpress (as required by many journals).

NASCArrays

 

In NASCArrays- all data can be downloaded for free with no strings attached.

All files are available by FTP - This includes raw data from the Affymetrix machine, including CEL files.

Donating data

NASC generates about 500-1000 chips per year in-house but we also host external data. If you want to donate data to us it will be incorporated into our database and made public through several means for you. Please see our donating page.

NASC was a core part of the AtGenExpress project and the experimental data was first made available through NASCArrays and AffyWatch.

Some analysis hints

The Arabidopsis Co-expression Tool (ACT) at the University of Leeds uses NASCArrays data to calculate gene co-expression patterns - useful for putting the role of each gene into a wider biological context of other co-expressed, cooperating or anti-correlated genes.
