What exactly do you mean? In every solution, every molecule transiently 
interacts with another molecule (they hit each other and then have higher 
or lower chances of staying together for some time).

Do you mean that the association constant is so low so that 
half-time of the complex is very short? 

Or you mean that there is some high affinity interaction which
is disturbed by a third party in a timely fashion? 

The approaches, I think, would be very different. Also, it is 
important to know what system you have - in vitro or in vivo, 
whether you are dealing with pure proteins available in large 
quantities or not, etc. There are so amny ways to study 
interactions between molecules that the answer to your question
becomes impossible without knowing what's given.
