  For that you need two functions to react with each other. One on the protein and one on your drug. You want that the protein will react only with the drug and not with itself. For that you make the reaction selective to the drug. Which means the function where you will attach the drug can react only with the one on the drug.
  
  Then conjugation reaction are done in aqueous solution and are dependent of temperature and pH.
