Abstract
Abscisic acid (ABA) was functionalized at the 3′-position by reaction of its α-2′,3′-epoxide with 1,4-butanedithiol to afford the corresponding derivative having a six-atom linker arm containing a terminal aulphhydryl group. This derivative was coupled with epoxy activated Sepharose 6B affording a gel containing ca 1.4 mg of (+)-ABA ml⁻¹. This gel was shown to bind specifically an anti-ABA antibody from hybridoma culture broth, and its binding capacity was determined. The (+)-ABA analogue possessing the thiol linker arm was also derivatized by reaction with a fluorescent derivatizing agent and these compounds were shown to inhibit cress seed germination.
