translucent PVDF membranes

[vaughan at sci.wfeb.edu]

Hello Fellow Western Blotters,
	I have been using PVDF membranes for Western blots recently, and have 
noticed that the membrane becomes translucent if "too much" protein
is loaded in the lane. 	This is a problem since the blot does not become 
opaque again after it is dried. 
	Has anyone else seen this problem, and what have you done about it?
	Thanks for any imput.
