I guess I'm confused: The conformational antibodies often will not work in 
Westerns since the protein is denatured by SDS. If you want a good 
blotting antibody for ras, you probably should use 146. I don't think 
that's conformational. However, I think that 238 and 259, or at 
least one of them, is conformational. They can be obtained from Santa Cruz 
or UBI. They're (I think) not great in blotting, but work well in I.P.
