Eleven hybridoma clones which secrete monoclonal antibodies against purified rat liver alcohol dehydrogenase (EC 1.1.1.1) were isolated. Antibodies (R-1-R-11) were identified by their ability to bind to immobilized pure alcohol dehydrogenase in an enzyme-linked immunoadsorbent assay, in which antibody R-9 showed the highest binding capacity. Except for R-1 and R-7, all antibodies inhibited catalytic activity of the enzyme isolated from inbred (Fischer-344) or outbred (Sprague-Dawley) strains (R-11 greater than R-9 greater than R-4 greater than R-6 greater than R-10 greater than R-8 greater than R-2 = R-3 = R-5). The inhibition of enzyme activity by antibodies was noncompetitive for ethanol and NAD+, and was dependent on antibody concentration and incubation time. Antibodies R-4, R-9, and R-11 were most effective when enzyme activity was assayed below pH 7.7-7.8, a condition thought to protonate the enzyme's active center. These three antibodies did not inhibit horse liver alcohol dehydrogenase activity, indicating their species specificity. Such antibodies will be useful to delineate structural and functional roles of rat liver alcohol dehydrogenase.
