Defining protein contents and variation of some human body fluids

 

This might not be the most exciting "news" topic (who named this thing?) but I had trouble finding this paper and thought it would be worth putting it up (again?). 

How much protein is in saliva again? How much does it vary from person to person? What about plasma when it's depleted, or not? Maybe there are other references, but this is the one I had saved in my old free citation manager and now that I work somewhere that uses the fancy pay for ones, it's now saved in it.
