1.Immobilized CoA has been obtained by reaction of the diazonium salts ofp-amino-benzene-sulfonyl-ethyl (ABSE)-agar with CoA solution at roomtemperature.2.The amounts of CoA immobilized increased with increasing numbers ofaromatic amine groups on the support.3.The coupling reaction of ABSE-agar with CoA proceeded easily and wascompleted within 30minutes.4.The significant effects of pH on the coupling rate of CoA and the SH-groupof the immobilized CoA were observed.In general,the coupling rates were muchhigh...
