Alkylammonium acetate buffer systems have also attracted limited attention for the separation of tryptic digests of proteins on octadecyl silica 60). The ammonium formate or trifluoroacetate buffers have also been used in the reversed-phase HPLC separation of the tryptic, chymotryptic, and carboxypeptidase A digests 136) of a-melanotropin and its N,0-diacetylserine analog as well as for enzymatic digests of the adrenocorticotropic family 137). Ammonium bicarbonate eluent systems have proved useful in mapping studies due to the eluent s volatility and differ-...
