Depending on the organism you could search in organism-specific databases. TBDB (http://www.tbdb.org) concentrates data for the Mycobacterium tuberculosis for example.

Standford Microarray database is accepted to be a very good repository of array data. http://smd.princeton.edu/

And, there is also Array Express : http://www.ebi.ac.uk/arrayexpress/

Thank you for your answers, I was particular interested in "Protein Arrays" instead of transcriptome / genome arrays. Array-express does also contain this type of data, I just wonder if there is some other portal that is specifically dedicated to this purpose.

yes offcource there are....................you can express your gene by using wonderfull software which i have used in one of my research work. that is Genemaths XT"

Hello Sabitri,

Thank you for the reply but there is a misunderstanding. I'm not looking for software to process microarray data. Im looking for a databases of ""Protein"" microarrays which are not gene expression microarrays with oligos, instead they use antibodies directed to proteins and not RNA/DNA.

PLZ go through my research publication.i have used this software but the operating of this software is little bit difficult. so be careful...............

Dear Marco,

Here some UniPROBE, Human Protein Atlas.
