<p>I am looking for an antibody database where each antibody is linked with its potential/actual target genes/proteins, <em>i.e.</em> a database similar to <a href="http://drugbank.ca">DrugBank.ca</a> but only for antibodies. It would be really great if the data is in a parse-able format, up-to-date and comprehensive enough to cover most of the common antibodies -- probably asking too much here</p>

<p>Any suggestions on this?</p>

Hi Arman,

Some of them are (Free+ Paid):

 - <a href="http://www.antibodyresource.com/antibody-database.html">Antibody Related Databases and Software</a>:

 > Antibody related amino acid sequencing tools, nucleotide sequencing tools, structural modeling tools, and hybridoma/cell culture databases can be found below. Speciality research databases that include monoclonal and polyclonal antibodies are also included.

 - <a href="http://www.hupo.org/research/hai/">Human Antibody Initiative</a>
 > The mission of the Human Antibody Initiative (HAI) aims to promote and facilitate the use of antibodies for proteomics research. The initiative consists of two separate activities; (1) the generation of a catalogue of validated antibodies from many different sources and (2) a protein atlas for the expression and localization of human proteins in normal and disease tissue. The two separate activities have as their primary deliverables to generate databases with free public accessibility. 

 > - The <a href="http://www.antibodypedia.org">Antibody Resource database</a> is aimed to produce a comprehensive catalogue of validated antibodies towards human proteins. This initiative depends on input from a large number of academic groups and commercial companies.
 > - The <a href="http://www.proteinatlas.org">Protein Atlas initiative</a> is aimed to provide comprehensive and annotated database of high-resolution images showing tissue profiles in normal and cancer tissues. Both databases will be open to the public without restriction (no passwords).

I hope this helps a bit.
