Microarray to Protein Interaction Network

Question

[Ammu]

Hi,

Can I build protein-protein interaction network from available micro array data?

[russhh]

No, microarray data will not help you build a protein-protein interaction network. At best, you could use microarray data to predict PPIs that you can then test

Yes, you can build the protein interaction network based on microarray data.

Use the WGCNA package http://labs.genetics.ucla.edu/horvath/CoexpressionNetwork/Rpackages/WGCNA/Tutorials/

Dear Pyperl, Thank you very much but the tutorial in the link in to build gene network from micro array data set.

Note that gene co-expression networks are not the same as protein-protein-interaction networks.
