A technique for quickly detecting nanogram quantities of low- and high-molecular-weight inhibitors of some serine proteases is described. The inhibitor solutions are spotted onto agar films which contain either L-1-p-tosylamino-2-phenylethyl chloromethyl ketone (TPCK)-trypsin or tosyl lysine chloromethyl ketone (TLCK)-chymotrypsin. Enzyme
