yes, you'll need buffer, salt, stabilizing agent(s) (edta, dtt, ...). normally you should include protease inhibitors but since you are trying to purify a protease you should omit them (or, at least, the ones that will inhibit your protease of interest). if you omit then you will have to work quickly and in conditions which will reduce proteolytic activity. you also should hope that your protease of interest doesn't autolyse.
check the literature to see if others have purified your protease or a similar one and the conditions they used.
