A highly sensitive, inexpensive, and facile bioluminescent assay for the de
tection of catalytic antibodies has been developed. This assay may be used
for the early detection of antibody catalysis. The efficiency of this techn
ique was exemplified by the use of the luminescent bacterium VhM42 for moni
toring an antibody-catalyzed retroaldol fragmentation reaction with aldolas
e antibodies 38C2 and 24H6. (C) 2000 Elsevier Science Ltd. All rights reser
