  At the risk of sounding rude, you might consider reading something about 
protein purification before launching into buying things.  Firstly with an 
acidic protein you would not likley use a cation exchange column.  I would 
suggest you check out any basic biochemistry lab manual and you will find 
guide lines for how to plan a purification.  You also need to supply more 
information about your protein if you want suggestions about purification.  
This is not meant as a flame, as a I think you have posted to the right 
place for help, but to be able to decide what to do with the advice you need 
some background :-).
