A system for the immune mediated in vivo hydrolysis of the nerve agent sarin, comprising metalloantibodies capable of hydrolyzing the nerve agent sarin, a cell culture method of raising these antibodies, an artificial antigen capable of stimulating the production of these antibodies, and a hapten analogue of sarin. A hapten analogue to sarin is formed by conjugating a Cr(III) trien with N

-di(O,O-diisopropyl) phosphoryl L-lysine (DIP). This hapten is conjugated with key limpet hemocyanin (KLH) to form an antigen capable of eliciting antibodies with reactive sites for both metals and sarin. Antibodies formed in response to this antigen are cultured in an immortal cell line and purified. The steric proximity of binding sites on the antibody for the metal trien and sarin allows hydrolyzation of the F

moiety from sarin and sarin's resultant bioactive neutralization. Antibody hydrolysis activity is monitored by measurement of produced F

Two long-chained cupric ion complexes were synthesized and found to possess remarkable catalytic activity toward phosphate triesters, diesters, and other phosphorus(V) compounds (including some particularly toxic and persistent materials). The complexes form metallomicelles which bind substrates with enzyme-like efficiency (K/sub assoc/ > 10/sup 5/ M). Rate accelerations approach the 10/sup 5/-fold
