This should be working. What are the electrical parameters of your
transfer protocol? We've had success blotting to nitrocellulose in a
semi-dry transfer cell at 10-15 V, >300mA for 70 minutes. The transfer
buffer you use seems fine: we use the same thing. What exactly are you
seeing with the Ponceau stain? Does nothing on the membrane stain, or
does the entire membrane turn red?
