About NASC's International transcriptomics service
- Any available species (e.g. Human, yeast, barley, wheat, bovine, tomato).
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
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.).

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.
There is NO EXTRA CHARGE for failed samples.
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.
AffyWatch, is our low cost CD subscription service. 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 sent out on AffyWatch for you. Please see our donating page.

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.
Future Developments on Analysis
Some very exciting things were draft released in the summer of 2007 (full strength in Jan 2008)For a preview see this introduction to Genespring Workgroup.
