western blot of antioxidant enzymes(GPx,SOD,CAT)

[thomas at sbrc.umanitoba.ca]

I am a M.Sc. student at University of Manitoba, Winnipeg, Canada. We are 
working on  protective effects of antioxidant on Adriamycin cardiomyopathy by 
investigating antioxdant eznyme gene expression in the heart of rat. It will 
be highly appreciated if any experts give me some information about sources 
of antibodies of GPx, SOD, and CAT, as well as M.W. of these enzymes in rat 
heart.

Thank you!
