Dear Ying Fang,

Basicly, one normally starts with developing an assay ans then takes some 
crude material like liver homogenate or whatever an first used crude and cheap 
methods (preparative ultracentrifugation, ammonium sulfate precipitation) 
before one advances to ion exchange chromatography, size exclusion, 
hydrophobic interaction chromatographt, affinity chromatography.

Exceptions occur on specific properties of protein of interest.

You might visit your library and look for 

current protocols in ... (e.g. protein chemistry)
... a practical approach (series), e.g. ultrazentrifugation

Biochemistry? by Cooper

find some papers about protein purification examples and see how they did it.
etc etc
