cDNA matrix

[Mark J Swanson]

Hi,

I am looking to do differential display, and I was wondering if anyone 
has heard of a company that sells a cDNA expression array for S. 
cerevisiae.  Clontech sells them for Human cDNAs.  I had heard that a 
company called Affimatrix may sell them for yeast.  Does anyone have any 
information?  Also, what kits would be best for differential display in 
yeast?  Thanks in advance.

Mark
