Sometimes binding the antibody to the beads first and adding the lysate 
reduces background.  Also it may be worth analyzing your results 
using  glycerol or sucrose gradients.  You should be able to 
coprecipitate the two proteins from high MW portions of the gradient, but 
uncomplexed proteins in the lower MW portions of the gradient  will not 
coprecipitate.  This method has been used to show that hsp90 and src interact.

Good luck,
